Yes, cant see anything suspisious. I will take the head of next week. I need a break from this car, I will play with my boat in the weekend instead, going out to one of the smaller islands and breath... There are more than 6500 islands in our archipelago so I can easily find one where I can be alone for a while.

Pete Lewis Posted August 4, 2023 Report Share Posted August 4, 2023 (edited) valve guide fit ...... go back to the school science test with heating a ring with a ball sitting in it as the ring is heated the ball drops through so as the head heats it can loose its grip on the valve guide hence the ok cold misfires hot and observation shows little oil feeding the rockers there should be a pool of oil near no 6 due to the angle of the engine is there a snag with the interupted rocker feed ????

No, there was a pool of oil near no 6, but it is difficult to see on the film. I actually had to turn off the engine because oil started to flow from the pool down on the clutch and I was worried that it would reach the clutch. I will remove head next week, now out with my boat for some mindfulness and contemplating time... Link to comment Share on other sites More sharing options...

Roger, Just checked on the original cylinder head fitted to my engine and and couple of spares, that dowel is 1/2" (12.5mm) long and the nut is accessible with a socket. Out with the cutter is probably easiest as the head is now very stable. Dick Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 5, 2023 Report Share Posted August 5, 2023 so if it is pooling at the no 6 then i am right its down the clearance between head and guide , there is no other way you get oil on the back of the valve head and when the valve opens it should get sucked into the combustion chamber there is something silly going on in that area cant swear to that but how else is neat oil getting where it is ???

Roger Posted August 6, 2023 Author Report Share Posted August 6, 2023 Boat trip cancelled due to rain. Lots of it. No cracks found so far (thank God) but only a quick check done. Will clean and remove valves and look closer. Link to comment Share on other sites More sharing options...
Roger Posted August 6, 2023 Author Report Share Posted August 6, 2023 I will of course have to order a new head gasket, valves, bolst & nuts etc. I know there is plenty of information about head gaskets on forums, but the ones that people used to recommend seems to have been discontinued or the supplier have new owners / management with detrimental impact on quality. Is this a good choice? https://www.chriswitor.com/proddetail.php?prod=207102AF Link to comment Share on other sites More sharing options...

Roger Posted August 8, 2023 Author Report Share Posted August 8, 2023 (edited) My cylinder head from early 1966 Vitesse HC engine seems to be identical with the one I have on the MB engine I have from a 2000 Mk I. Just out of interest: Are the stamped numbers serial numbers unique for each item, or some kind of batch number? (515440 from blue HC engine & 514271 from black MB engine) Edited August 8, 2023 by Roger Link to comment Share on other sites More sharing options...
johny Posted August 8, 2023 Report Share Posted August 8, 2023 I think theres a casting number and then the stamped number identifies the head after assembly. Yours should have the same casting numbers but what the differences (if any) of the assembled heads are I cant tell as the information available for mk1 is pretty limited.... 1 Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 10, 2023 Report Share Posted August 10, 2023 doesnt cover all but CW has a comparison chart but mainly big saloon heads head_applications_chart.pdf (chriswitor.com) Pete Link to comment Share on other sites More sharing options...
Roger Posted August 10, 2023 Author Report Share Posted August 10, 2023 (edited) Thanks @Pete Lewis Very useful information! Only for Mk II models, so I had to check the numers on the cylinder head from my Mk II PI engine and it seems like it has the original CH stamped 218225. I also have a very rusty and seized 2000 Mk II engine from a Saloon. One day I will have a Mk II engine in my Vitesse and get rid of those pivot clamps for inlet/exhaust, I don't like them. This engine was supposed to be a "quick fix, use as is". I never learn... I have ordered parts from CW. It took a while for him to figure out PP and which carrier to use for The Aaland Island, but parts are on the way now. Just a few weeks of transport, the usual customs bureaucracy ordeal and then I put it together again. Plenty of time to clean the surfaces.

Roger Posted August 25, 2023 Author Report Share Posted August 25, 2023 (edited) Some engine porn for you here. My local engine builder found that the head was warped quite a lot. Not anymore. New valves etc. It was not as expensive as I though, well worth the money imo. Might be driving out and about on Monday with a bit of luck... I also found that the washer under the nuts was not the thicker hardened ones. The head came off almost too easy...
