The next step in your thorough investigation is to remove the head and visually inspect the innards; there is no other testing from outside the engine that will tell you anything.

I am reminded that I have spent thousands of dollars denying a pet had terminal cancer, more times than I am willing to admit. I do understand.

 

Thank you. I had wondered this too. Stranger things have happened and I wouldn't be surprised to see it here. I will know better this weekend after I pull the injectors for inspection. I'll apply new seals and re-run the compression test. I'll then drive it a few days to see if the CEL returns on #4.

Are they standard sized bore or oversized? If I rebuild, there is a possibility I will bore the cylinders. Are the domes stock or are they performance?

 

They are standard bore since they came out of a stock LNF. I replaced the pistons with and rods with forged Wiseco and carillo rods

 

 

Are the sleeves replaceable? Or does the whole block need replaced?

 

 

Awesome! At least if I find that the engine needs rebuilt, I can just replace the sleeves and pistons, rather than worrying about boring it. That makes things a little bit easier. Thanks for the feedback!

 

Guy can afford the tool but not a decent engine stand????

 

I noticed that too!! Hahahahahahaha!!!!!

 

I wonder. Do they recommend freezing(shrinking) the liners to make installation easier ?
I remember doing that years ago when replacing the liners in a small diesel engine for a customer.
