I think I killed my engine :(

[Uberoo]

I took my subaru to a local mud bog.Out of the blue my SPFI conversion started acting up and would randomly stall the engine then it wouldn't fire again for a long time(like 30 minutes).When it ran I was easily outclassing the other 4's.Then it would stall out and I would loose.I will take the harness out and inspect every wire to see if I am intermittently making contact with something.Not to mention pull the dash to eliminate any such problems.

 

As for killing my engine,I had my airfilter mounted back in the spare tire bay so I thought it was reasonably protected.After the first mud race it was so full of mud that it started pulling the mud through the filter and into the engine which is what I think caused the first stall.After that it cranked like I had no compression.so I pulled the intake hose and it was running straight (filtered) mud into the engine.I pulled the plugs and all four had liquid mud on them.So I cleaned them out and re-assembled the engine.I got it to start by pull starting it.It smoked alot of oily smoke out the exhaust whenever it was running.Got it idling and I think I started hearing a faint knocking sound.I tried to drive it around to where I could load it on the trailer and it stalled again.Try as I might I could crank it would fire for about a second then stall again.Still havent been able to get it to fire.it won't even fire when pull starting anymore.Great.

 

I will clean everything up then start taking the engine apart and see if it is salvageable.I think my next engine I might stuff some EA71 pistons in with the SPFI.Then run a snorkel.

 

owning a 4x4 is definably a labor of love.As of right now: my engine is dead,im having wiring issues,and the right front caliper/rotor/pads are messed up because at some time before the mud bog a caliper bolt came undone.
