Following a hydraulic tappet noise and dismantling the engine

This answer was rated:

Following a hydraulic tappet noise and dismantling the engine (120,000 miles) the garage found it was worn out generally. We bought a breakers engine allegedly 51,000 miles and had this installed with new cambelt whilst on the bench (this is 2 lt turbo diesel crtd, 2003). The "new" engine certainly looked "clean" as if it had only done approx. 50,000 miles. They had to use the injectors from the original engine with new injector seals.
When started, the new engine has a lighter "tap" which is apparently hydraulic tappet (but you have to buy 16 of those x £35 to id it. Also it sounds rough and noisy and is a poor starter. Local garage (excellent engineers) say this is poor compression with the engine starting on one or 2 cylinders at first. Only solution, is stripping engine again! Or do we give up?
Could the use of the earlier injectors be causing the problem? Any ideas, thoughts, very much appreciated. We'd love to keep the car, but running too rough!
Many thanks

Hi .

Stop !!!
Before stripping i suggest you do a engine oil flush ,this will clean out the hydraulic lifters
as this engine has been probably stood for a long while .

20 minute flush with cyclo engine flush ,then drain and replace with good engine oil and filter. (The can will say 5 minutes ) Do 20 minutes but leave at idle do not
rev the engine .

This normally works but if it does not check with the engine supplier for another engine
if you open this one you will loose the warranty ..

If no warranty then go ahead and have the mechanics check this out for you.
