Valve/lifter problems.

[Jonny81191]

Yeh uve got a valve just stuck open a tad, u can hear it dropping comp on one cylinder..

Tom it wont hit the valve, would only do that if the valve was stuck entire way open, but theres no timing issue, so even if it did it would just push the valve home, not bend it.

The reason i asked if u had oil pressure gauge is cos as Ruan stated, when u loose oil pressure the head gets dry and things start sticking, this occurs all the time with xuds that have been off road for ages, but for it to happen with a working again suggests something shitted..possibly a lifters pissing oil, but doubt that, possibly collasping lifter causing the rocker to jam, but id say more just a general lack of oil pressure for some given reason, has it been making big power with the blower?

Whip the cover off and see wats kicking off, either way, welcome to diesel tuning

Was making big ish power but not much over what it had already been doing for months TBH
