So doing a valve adjustment i found #3 intake to be very loose. I started to adjust and then found this. Why/how did this happen?
Also, why are my leakdown tests consistently 20% leaking through the case? Rings? I did it cold and the engine looks to be rebuilt from how clean the inside of the heads were.  |

The adjusters do wear,once the hardening has broken away you get your problem,this is often compounded by too much clearance. I never refit adjustment screws that are too worn,its just not worth it,you will need to check the end (tip) of the inlet valve isn't damaged which I fear might be the case. Try a compression test with the engine up to temp ,a cold air cooled engine takes up a fair amount with expansion,if your leakdown test is even 20% it will improve when hot so you should be fine. Good luck. |
