Just refitted the engine after a pair of 2nd hand heads and turbos. Been assured that the heads are from an auto, same as mine and were nice and quite before breaking. Car is all rebuilt, new platty plugs, oil flushed and replaced with Magnatec, new filter etc

Car has not been driven as yet, only started and all the niggly bits sorted out, but here comes the problem !!!!!

 

Helluva tappet rattle :mad: Been advised to drive it and the tappets will fill with oil and pressurise, but it goes against the grain to drive something that doesnt sound right. Double checked the timing marks and it seems ok, pressure test each cylinder and thet pan out at around 150/ 160 psi each cylinder.

 

Will i fook it by driving it for a test run ???

Any help will be gratefully appreciated.

Cheers,

Alan.....

Is there any thin oil that could be used, even short term to get the oil flowing through them ??

Or is it the case that when there shut, thats it ??

you could try an engine flush - get it nice & hot with that in, drop it out & refil with oil

Already tried that. Used stp engine flush, add to a warm engine, idle for 15 mins, dont drive and then dump and re-fill with fresh oil and filter !!

Thinking about road testing it, if no change then putting new flush back in, leaving it a few minutes longer and then trying it. An old timer at work said this problem was common on early Cessna Aero engines. The cure there was to drain a litre of engine oil off, put in a litre of ATF and run it for a short while. The hotter it gets, the thinner the ATF becomes and will find its way in anywhere !!! He also said that an egg in the radiator will cure a small leak

:( Sounds more like a Gordon Ramsey solution, but as they say, Desperate times call for desperate measures !!!!

 

Alan...

Magnatec, I wouldnt put that in me lawnmower. Go buy some Carstrol RS 10/60w or mobil 1 Motorsport 15/50w. Millers do a nice 10/60w aswell.

Where can I get some Castrol RS 10/60 from Chris ?

Going to try it on Sunday !!!!

What the hell, its only a car !!! :cry:

Good luck mate! :)
