Hi

My trusty Isuzu 1.7d. (x17d) engine is starting to sound like a bag of nails. Lol.

It has done 120k but recently has started a loud tapping noise from top of engine ?

I remember on my old nova I adjusted the valve clearance gaps etc and have mates who are talking about hydraulics lifters. Etc.


What do u have and what can I check/adjust ?

Thanks

Never heard of shims before guys ?

Could these have worn causing the noise ??

So there is no adjustment, i just have to replace shims ???

Why give a clearance value if it is fixed/non-adjustable.

Thanks

Cheers guys.

I understand what clearance us and why it's required.

What is the exact procedure to measure.

I take u will need to crank engine to turn respective valves to closed position to measure ?

Will get a manual as suggested.

Where would you get a requires shim from though ??

Been googling and can not find anything ???

Cheers
