My question concerns hydraulic compensator noise. I tried changing the oil 3 times at 500 mile intervals and that did not work, nor did replacing Delvac with synthetic. Upon inspection for the 110k mile timing chain replacement the engine appears clean, there are no broken timing chain guides or oil tubes and the cam and rockers look to be in great shape. I think the noise is coming from #7 cylinder valve compensators. Rather than replace all the compensators on this side I was wondering if anyone had either cleaned the old ones or by inspection found which one was not functioning properly.

At 110,000 miles I am heavily into the front of the engine, after reading all I can from here I will replace timing chain, tensioner, guides, oil tube fittings, belts, hoses, water pump, thermostat, heater hoses, mono valve and those nasty allen head bolts that hold the alternator support on.

Thanks for any help.
