I just think cams that needed to be swapped out for a car that has had very good maintenance and not driven partially hard needs to find the cause.

The camshaft fear is from back in 2 valve, OHV daysOhv engines run STUPID stiff springs to get all that weight away and let the valve close. So if an engine oil had low zinc it round its cams in no time.It was more of a bad engine, than bad oil Link to comment Share on other sites More sharing options...

And the result is exactly what is seen in the photos. 1 Link to comment Share on other sites More sharing options...
turbotrana Member 2,586 Member For: 21y 20d Gender: Male Posted 09/06/14 01:39 PM Share Posted 09/06/14 01:39 PM Are there any billet steel cams for these engines. This will solve the problem as small rollers (like a Expensive Daewoo VN V6) don't really like cast iron but a large roller as on the e-series never causes problems. A medium sized roller with poor hardening might just cause issues sometimes. Link to comment Share on other sites More sharing options...
