[&:][&:]Help engine info needed

[912UK]

Hi Can I pick some brains please I am very concerned about a 912 engine that I am helping out with and want to know what you guys think.

The engine I think over heated and it was alowed to cool down before driving back it drove back fine . It was a very very hot day and I think this contibuted to the problem . The car was parked up and alowed to cool.

When I checked it out I made sure the timing was correct and ran the car to do a quick test it poped and banged but ran. So I switched off and alowwed to col (next day) I then checked the valves they were all tight so I backed them off. reset them. Now 1 and 2 reset fine. But 3 and 4 inlets where fine once adjusted but 3 and 4 Exhaust I have backed right off and I can' t get the feeler gauage in to check a gap .This is because there is no gap. now ,what would be the problem I think I knew and and have a few ideas but I would like you guys to comment.

One idea from a guy I spoke to was to take off the rocker gear and shim it out then adjust the tappets but I am fightend that there is a more serious problem .

Do let me know

Cheers

M

When it got hot did it stop or just go sick? I assume that the fanbelt snapped?

They normally say that if it has been run hot without any air going around, it will only normally run for a few minutes before terminal damage has been done. It may be worth popping one of the heads off to see if there is anything obvious there.

Sounds potentially expensive!

There are two morales there though -

1) make sure that the generator light works on the dash

2) that the person driving knows to stop the car as soon as the light comes on!

I' d be interested to find out what the problem actually is.
