wimpus Posted January 17, 2021 Report Share Posted January 17, 2021 Hi. 6 Months ago fitted another head, headgasket, pistons etc after 305.000km and 42 years old. Now after 10.000kms the headgasket went, coolant getting out of the rad, day after white smoke out of the rear. Head is getting a light skim as not fully flat. Now I was cleaning the block and found out the cam followers are again pitted. Looked at the cam.. also pitted 😕 Link to comment Share on other sites More sharing options...
Nigel Clark Posted January 17, 2021 Report Share Posted January 17, 2021 That's disappointing. Did you fit a new camshaft and followers when the engine was rebuilt 10,000 km ago? And was any new cam ground from a new blank or a regrind on an old worn cam? Nigel Link to comment Share on other sites More sharing options...
Pete Lewis Posted January 17, 2021 Report Share Posted January 17, 2021 looking at the way the fire ring has given out i suspect a loss of torque on the head studs the head has been ' panting' looses grip on the rings answer Nigels lead and that will help with the cam/follower wear Pete Link to comment Share on other sites More sharing options...
Sparky_Spit Posted January 18, 2021 Report Share Posted January 18, 2021 Hi Wim - I had similar problems with the gasket fire rings burning through just where the meet the blind jigging holes near cylinders 1 and 4. I suspect that the resulting lack of support for the gasket material behind the fire ring creates a weak spot. I filled mine with brass plugs, epoxied into place.

Pete Lewis Posted January 19, 2021 Report Share Posted January 19, 2021 well years ago i had a rattley 78 Talbot Alpine , typical Simca clatter , cam was like bird siht on a shaft followers well concaved managed to win a cam from the factory but not followers, and they cost a lot so with pillar drill and wet /dry spun them to a flat finish sold the car it lasted 100k since and stayed quiet , tappet adjusters were a bit on the limit but ...it worked till tin worm caught up Pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted January 19, 2021 Report Share Posted January 19, 2021 Have got boxes of new ones, plus a few spare cams... so will just use plenty of oil at the start and keep my fingers crossed. Link to comment Share on other sites More sharing options...

Pete Lewis Posted January 19, 2021 Report Share Posted January 19, 2021 there has been over the years a number of engines with supposed upgraded bronze valve guides that ended up with an early valve seizure so do serious homework before going down this idea , same as fitting oil seals to the guides ends up with a stuck valve as lacking designed lubrication just be careful before you make more problems Pete Link to comment Share on other sites More sharing options...

PeteH Posted January 20, 2021 Report Share Posted January 20, 2021 HI. Having looked now at the other post, I can see where the issue lies. There is little or no support for the Gasket at that point, and the seal is relying entirely upon the Torque spread sealing the fire ring. Any, even minor, distortion in the Head/Block interface will show up the weakness. I can see now why the other poster filled them. As they are "allegedly" just blind holes to assist the O-E machining process, why have the hole punched into the gasket anyway, IMV it only weakens the gasket?. Does anyone do a Head gasket without the holes.? My interest comes from the fact that in order to investigate a low compression Pressure on the 13/60 Engine, I am going to have the head off and it will be interesting to see if the same holes and gasket arrangement apply there also?.

Income tax is more then the parts. And time.. I guess they were more concerned about fish than Triumph spares when they negotiated the deal. I am surprised no European supplier does them though. Hopefully you can quickly engineer the modification for the void, should stop the gasket failing again. Link to comment Share on other sites More sharing options...

And nothing to do with Brexit either (my View) Import duties are levied for many items. And always where. I had to have an Alternator shipped from Belgium to France, where I was "grounded" when the one on my R-V (American Camper) failed big time. The freight and Tax (pre Brexit 2006) was in excess of the cost of the item!. Getting "stuff" from the USA was always a case of "Double the US cost" by time it landed on the driveway!. The same applied too on many items stocked throughout the EU. VAT rates accross Europe varied by Country. At one time the UK rate was well below the rate(s) in many EU countries. Going forward, I can see once the "teething issues" are ironed out that very little will have altered in real terms. Pete Link to comment Share on other sites More sharing options...

Pete Buying goods within the EU in one country for delivery in another EU country shouldn't have caused extra taxes. You should have paid the VAT in the exporting country and no more on arrival. The paperwork might well have shown a price Ex Vat, the VAT and then postage. Before the UK pulled out I bought lots of my spares from Britain, paid the price including UK VAT, postage nothing else. It will be interesting to see what happens now. Rimmers did send out a mailing to confirm that they will continue to ship to the EU. Prices will be ex Vat and any VAT/import taxes should be paid to whoever delivers the parcel. "A suivre" . . . . Link to comment Share on other sites More sharing options...
johny Posted January 20, 2021 Report Share Posted January 20, 2021 The VAT part seems clear enough but I cant understand how the import tax on items going between UK and Europe is going to be worked out and at what stage. My take on it is that if it has been wholly made in the UK or EU then theres nothing more to pay (Brexit agreement) but if part of it has been brought in from outside then someone has to calculate the import tax that generates. I think this will be highly complicated and probably just be a tax on the value of the complete item which the customer wont know until it arrives!
