Rv8 Gems lifters bleed down. HELP!!

[lostinspace]

Hi everyone,

I have recently completed a rebuild of my Defender 50th 4.0 Rv8 Gems engine.

Everything is new in the engine and it runs nicely, but the lifters are bleeding down overnight and it’s driving me mad to hear that rattle on every cold start.

Any pointers to the cause of bleed down would be appreciated.

Thanks, J

Check tappet clearances. Sadly the inlet manifold has to come off for that!

Thanks Chris,

I thought I had understood and set the pre loads, but I will take another look.
Yes the inlet removal is a PITA….

Cheers for your reply, J

Is it the right grade oil?

My engine used dinosaur juice 20W50

Not sure what was specified in the Gems engine…. Perhaps it has old style lifters that are expecting the old oil stuff
