The demise of the 9.5:1 turbo engine

Featured Replies

Ok, so i was cleaning up the heads from that engine...and all of the exhaust valves are WHITE...except for cyl#1, it was covered in unburned crap. After hitting it with a wire brush...what do i find? A peice of the valve is burned away!! Spray brake clean around...and it runs out the exh port. Well, there was my no compression culprit...now, i think it all comes together...i tweaked the vane air flow meter, more spring pressure than stock evidently, which caused the engine to run lean lean lean. Too hot, rings gone on #1, and the valve burned as well. It did run a little warm on the Interstate as well...and no wonder I was getting 29 mpg! So, ive got to turn it back before I put the AFM back in. Also...i need to take the valve out and replace it. Gotta find a valve...found one! Oh, its 50 miles away...so I can only get 1/2 the engine put together today. *sigh*

i have a complete cylinder head for the #1, and #3 cylinders. it has a small crack in between the valves, but worked fine on my car. it is off a 87 ea82t wagon. if you are interested im me and i will give it to you for free, minus the shipping. you pay that.
