Hello Folks!

I have a 2000 5.4 Triton. I removed the timing chain cover. The driver's side chain ate a hole into the oil pump. This was a new chain with new guides and tensioners. I bought the truck with warped heads. When I took the engine apart to fix this issue, I noticed that the original chain had broken chain guides and slight grinding on the oil pump. The passenger side chain had been grinding on the timing chain cover. I had the heads fixed and bought new chains and timing stuff mentioned above. I replaced all exactly as it was removed. Any ideas why the chain is doing so much damage? Are there spacers or something ? thanks..

So I just read a post about crankshaft thrust washers. I will have to check the play in my crankshaft. Sometimes, it's not easy to find posts related to one's problem. I will investigate this issue and hopefully be able to correct the problem. I can't afford to redo the block. I hope I can correct this issue without pulling the engine and having to have everything redone. I just has to last a few more years. Any thoughts? thanks... I will be looking up crank thrust also.
