    Spark plug colour

    Morning Johny he mentioned that there had previously been a repair on the main bearing cap and that it was probably that that had led to the failure. Joef - I agree with your diagnosis of the price and condition of the mk3 engine - it would be my first choice due to location- the block and crank are going to have to be reconditioned regardless so my main concern is that the crank is in good condition. I really need to have a look at it first to make sure that I’m not buying another engine with a ton of trouble built in. cheers john

    So I took the engine to the guy that rebuilt it to have a look at. Whilst I was there we drained the oil which had some worrying silver swirls in it! he called yesterday to say that the crank is scrap and it has also damaged the block, bit of a choker when only 10 months ago it was all re ground balanced and the cylinders bored etc. So the question is do I continue down the road of Old triumph engines or swap to a modern probably MX5 engine? I think I've answered my own question in as much as I don't have enough enthusiasm, skills or time for the MX5 swap. So I'm looking at replacement 1300 engines, there are 2 on EBay at the moment a spit 111 (11584581167) which is described as rebuilt and dry stored. It looks clean and has obviously been painted with a grey primer and left to attract some surface rust. Or a 1360 engine (38572400958) This one looks un molested and genuine item. The first might be a genuinely well built engine or be a bodged mess and the latter might be a genuine low miles good engine or a completely knackered pile of scrap. Should I play EBay roulette or is there an alternative. Cheers John

    Thanks Johnny - engines going to come out and go back to the guy that re-built it. Hopefully there will be no damage to the crank. I’m just a bit concerned as you say as to how they have dropped out in the first place. john

    So my love hate relationship with this car continues. I replaced the head gasket, retorqued after running the car up to temperature and it has been running really well including a faultless 30mile journey in the recent hot weather. Over the last few months I’ve been struggling to get it into reverse without any crunching of the gears, checked fluids - all OK. Bled the clutch and the old fluid was dirty and had a silvery appearance. (Time for a master and salve cylinder replacement I thought) Bleeding the system seemed to cure my gear selection problems. The day after my 30 mile run I went to use it and there was a horrible grinding noise. I thought that maybe there was a problem with the clutch thrust bearing so decided that the gearbox should come out. (Ford type 9 5 speed) With the gearbox out all of the clutch components were fine - my problem lies in the 10mm movement forwards and backwards of the flywheel. My assumption now is that the crank thrust washers have dropped out ( the engine was re-built at the end of last year) rather than worn out. Is it possible for the thrust washers to drop out and if it is what is the cure? Sorry for the long post and thanks in advance for any help John

    Thanks Steve might take you up on that . But I’m not going to be able to look at it for a while.

    It wasn’t Johny - I decided to leave be. The engine was rebuilt just before Christmas and I should have re torqued the head nuts - but I didn’t. So I’m hoping that some slightly loose nuts are the culprits. I’m not going to have time to take head off for a while though.

    oh why did i have to look under the bonnet - after all it was running fine! I took the Herald to Reigate (from Staines) to look at next weeks job , there was a a small possibility of a shower but I thought I’d take the risk. All was well the M25 is either limited to 50 or goes no faster than 50, heading up hill towards Reigate I went to overtake a lorry gave it some beans up to 70 then started loosing power pinking and getting hot. I managed to get home OK and did a compression test this afternoon 160psi on 1+2 but 10pm i on 3+4 , suppose i better order up a head gasket.

    Thanks Johny - I had thought that it looked that way - i’ll lean it off a little.

    Afternoon people can I have some advice please on my spark plug colour - too rich or too lean? many thanks in advance John
  11. Thanks Colin - I tried it the other way but it wouldn’t clear the engine block. i have an adaptor that i bought from SC Parts - part no. 285643 that fits the starter motor and can be rotated. should now fit with no more issues. That’s once i’ve got the engine back in the car. john
  12. Does anybody have experience of fitting a Powerlite starter motor (RAC401) to a 1300 engine. Mine appears to only fit one way, but is tight up against the manual prime lever of the petrol pump. Now I've never had a reason to use the manual priming lever but sods law is that once the starter motor is fitted I will. Thanks in advance John
  13. i’ve just bought some belts for a couple of projects from these guys: https://www.simplybearings.co.uk/shop/ The service was fantastic and prices were keen as well.
  14. Thanks Nick and Johny PH1 it is then - my gut feeling was for the PH1 but it’s good to have confirmation. I will check the oil pump next time i’m over at the workshop. Cheers John
  15. Update Having double checked everything again and still coming up with the same answers, I realised that whilst the thought of taking cylinder 3 out with the engine still in the car and the car in the drive seemed like a good idea (cheap) it was not going to be. The engine is now out and returned to the engineer who built the head. It’s stripped down and the rings on cylinder 3 fell out as the piston was removed. Initial inspection shows that everything is tired and bordering on worn out. So an easy decision has been made to completely recon the engine - cylinder bore, new pistons, camshaft, timing chain and sprockets, and oil pump, existing crank re grind and balanced along with the pulley, flywheel and clutch. I have spoken to Newmans ref the cam and it’s a toss up between the PH1 or PH2- the car has an SU HIF44 carb on a dolly inlet manifold and a stainless extractor exhaust manifold straight piped to an R1 box. Does anyone have any experience with the PH1 cam in a 1300 Herald, is it happy in normal driving about town or does it need loads of revs to be happy? Oil pump - whilst i’ve had no problem with the existing oil pump is there a source of good quality ne pumps and is there any real benefit to fitting a 1500 pump? thanks in advance for your help John
  16. Thanks Johny - I put 4-5 skirts from a trigger style oil can into the cylinder, I will re test with some more. Pete the head has new valve guides. john
  17. Thanks Pete and Clive - I will do a little more investigation tomorrow. When it’s running there are a lot of fumes in the rocker cover, would this change your joint diagnosis? john
  18. Good morning All So I fitted the rebuilt head, reassembled everything, including a new starter motor. With hi expectations of a now perfect engine I started it up and and adjusted the timing to its correct position. It was running quite roughly ( to the extent that the bonnet would rock about). I checked everything again including the HT leads ( plugs are all new). Still rough. checked the compression and I’m getting 130psi on all cylinders except number 3 which is down at 50psi. This was the same with some oil in the bore. I’m now thinking that this was the issue all along - assuming that this is caused by the rings failing to seal can I take the piston out from underneath with the block in situ and just change the rings or does this mean that the whole short engine will need to be rebuilt? thanks in advance for your advice. john
  19. Thanks Johny and Pete - I have new nuts from mini spares. Hopefully it will all be back together tomorrow and we can see if all the work will have been worthwhile.
  20. Afternoon all My head is back with new valves,springs,guides and seats. Prior to refitting i have cleaned all the old crud off the engine and noticed that the pistons have been marked with a punch, does this mean that it has been rebuilt in the past or would this have been standard from the factory. Also there is no marking for a top side of the new Payen head gasket - it would appear that it could be used either way - is this the case. thanks in advance John
  21. Thanks Chris - i will see what needs to be done.
  22. I’m taking my head in today to have it reconditioned. As far as i know it is completely standard, i’m running a single HIF44 carb on a log manifold with an extractor exhaust manifold and standard cam. Will it be of benefit to have the head skimmed to increase the compression ratio? John
  23. thanks for your thoughts gents - it’s going to a machine shop this week and whilst it is away i will carry out the paraffin test. we did put some oil in to check the compression after the dry test and the result was the same. Ho hum I guess it’s time to start spending some cash again!
  24. Now that its off I was going to get the whole lot reconditioned, the engine is the only bit of the car that is untouched since I bought the car. The bores look good to me with no scoring and no real signs of wear. My main concern was the the gasket and head show nice clean lines around cylinder 1 and between cylinder 2 and the same around cylinder 4 and between 3 and four, but between 3 and 4 there is a lot of carbon which looks to me as I've its not making a good seal at that point. Cheers John
  25. Hi Johny I've converted them to jpeg so should be visible now John
