- 98 mountaineer v8
BACKGROUND INFO: My 98mountaineer v8 has 254K miles on it, runs strong but needed something...tmh's and intake spacer. So in prep for that, i decided to pull some things off to do some checking....
First I had a set of old crown vic heads my buddy just rebuilt so i had something to compare them to.. I've been smashing my head into the fender trying to figure out why its running so lean..I've never thrown a code either.
My gt40p's are on the right, crown vic's on the left
Here is a list of mod's i've done, i've tried to see if anything i've done might have caused it, but have yeilded no results.
1.7 rockers, Cold air intake, cat back, modified the mass airflow housing a touch.... Nothing over and above what i should be able do without it being so drastic..
On another note I noticed the upper to lower intake gasket was wet on the back half with fuel. (I was thinking the valves were somewhat floating and letting some air/fuel mixture run back to the intake.
I have new, stronger valve springs i'm installing as well as a valve job on the head as the exhaust valves are pretty well shot. Heres some pictures
