bent valves on V6

Long story short, while changing spark plugs one broke and pieces of the porcelain shell fell into the engine. I thought I vacuumed all pieces out but I missed a piece. No compression on 5 and 3.


230k miles and the engine was still running strong.


Ordered a used engine with 108k that will arrive tomorrow. Today I begun removing the old engine.


I wish I already had ordered the headers, this would of been the perfect time to put them on.


Any helpful hints?

It makes a little more sense now. Was looking over in the parts for sale section and a thread mentioned you replaced the engine on a V6 G8. Unsure how much your used engine cost, but at one point, new ones were running slightly over $4,000 but that was quite a while ago. Best of luck on the repairs and getting her back on the road.

Total cost for the engine including shipping to my front door was $1025. The engine had the exhaust manifolds but I had to switch over my alternator, starter, power steering pump and A/C unit.
