Hi,

I just went back from dealership to fix the missfires problem and the technician notes cylinder #4 shows signs of worn piston rings and 70% leakdown. I know that the engine may run bad even I didn't feel anything wrong. The engine burn about 2qt mobil one oil per 5000 miles. Want to know if I need to swap another engine asap or just find someone to rebuild the engine?

Thanks for helping me

 

Well, if the cylinder walls are still in good shape... You could have a machine shop hone the cylinders, replace the piston rings, and replace those valve seals. A complete rebuild is unnecessary, unless you're going for huge power (aka turbo, sc, or N/A build).

 

Do you think it can last till summer? Since I don't have time to take care of the rebuild during the winter

 

Early years had a serious problem with gouging of the #4 cylinder... Honda paid for quite a few short blocks. It sounds like yours has come up later and the only answer is a new block most of the time.

 

I am wondering I would need the head or just the short blocks?

 

leakdown test should have told you where the problem was, either the head or the block.

used engine might be a cheaper option and I'd look into that before. Labor to work on the block isn't cheap. and it might be cost effective to find a cheap complete AP2 engine?

 

Save your pennies and sell your block for a project

 

Thanks guy. I should get a new engine. Do you think I should get it now, or wait till the engine totally stop working?
