Hey guys,
I have a 1989 Nissan Patrol GQ
About 6 months ago, dad was driving to work when he started hearing this from the engine.

The car has sat out the front of the house since then until now as i have time to work on it.
If someone has any idea whats possibly wrong with the engine i would be very grateful as it would make my life a lot easier when it comes to repairing the problem.
Thanks in advanced,
Mike
soundslike noisy tappet or lifter
rocker cover needs to come off to check
also when running put a screwdriver to different parts of motor and to your ear and listen
can give you an idear where it is comming from
Problem is in the valve train, when turning over I can hear that a valve is failing to seal.
Cheers, the ferret.
thanks for the reply, ill have a look tomorrow, get some pics of what i find
are there hydraulic tappets used in this motors? it sounds like a valve in my ears.
Guess, as it sounds very loud over the engine.
Rocker adjusting bolt come loose and push rod hammering rocker etc.
Or broken rocker.
Or bent push rod.
check rocker shaft for wear on the under side.
I recently replaced my shaft and rockers and now the engine nice and quite again.
no more tick tick.
good luck
Unfortunately, all the tappets are fine... :(
means i have to dig deeper
Ok that rules out the top of the Motor,
What about a bent valve as the Ferret suggests a valve not seating
only one way to find out.
Out with the spanners my friend, do these motors have a timing belt or chain ?
Maybe that's slipped a tooth
