Hi all,
I need advise, please! I'll try to describe the symptoms... Sorry if this topic has been up before, I didn't find any..
The noise has been progressing since we got the car about 3 month ago. I studied the manual, got a PRO friend standing by messing with his own car, and replaced the tappets and a broken rocker. Flushed and changed oil.
Put everything back together. the noises didn't go. Got down to rockers again, checked everything, put back together. same result. Well, new tappets sound much better.
The noise starts quietly just as the engine warms up to working temperature and grows louder. It's definitely not pistons or something, by the timing it's valve or camshaft related. it sounds like diesel from beneath the block heads, seems right-sided a bit. Then after a few seconds comes loud metallic clack-clack-clack noise from right side rockers/rods. The noise disappear when I rev up, but comes in at faster pace when the revs are at 1500 and slows down to idle. Metal clinging would come again only after few seconds.
a friend of my who's kindly lending me a spot by a garage with the tools, he's a good engine mechanic, works at official toyota. little experience with LR. He thinks the camshaft float-end is worn or the fixture inside the engine block is worn, therefore camshaft oscillation - and the noise, oil channel is misaligned and the oil pressure drops, and the tappets run in insufficient oil supply, hence the metallic noise later.
i'm all eager to work on the car but do I need to pull out the engine to get to camshaft oil bed? Is there anything inside the block camshaft related that could be worn, or do I just need a new camshaft? If you know any links to HOWTOs on this, please share. I would greatly appreciate some advise
