Hummer Guy Posted June 22, 2024 Report Share Posted June 22, 2024 We had a secondary timing chain and water pump fail 2 weeks ago, I've finally open up the timing chain cover yesterday and found out about this. A lot of the coolant was dumped into the oil in the process. My question, is there any chance the valve and piston is still good? I don't know if these are interference or non interference engines. I'm thinking about just replacing the timing chains and water pump but I'm worried about doing this and the engine is gone already. Quote Link to comment Share on other sites More sharing options...
Hummer Guy Posted July 7, 2024 Author Report Share Posted July 7, 2024 Update: water pump, oil pump, all timing chains, VVT solenoids, new spark plugs, and coils all changed. Engine is now running like its brand new, I'm honestly surprised. 1 Quote Link to comment Share on other sites More sharing options...
