CEL p0306 came on the other day. replaced #6 coil and #8 (cracked boot) and plugs. CEL p0306 again. Took to dealer and was told low compression on #6 and #8. Was advised to replace with updated cylinder head. Also the idle is low and funky. No ticking. Any Thoughts? Im in NY. Anyone interested or recommend somewhere for a head install? please help? :beer:

Maybe some of the city guys know of somewhere closer. I use Dennis Francis auto in scotia Ny. They do alot of work on triple threats race marauders and know good people who do motor work and I trust them.

did they give you the compression numbers they found? if not, then I would be leary. As most dealers make me leary anyway. Ever price a set of 4vdohc heads?

We've been emailing back and forth, but I'll post here too.

Call Keith McDermott at Quality Automotive in West Nyack. Tell him MartyO from MO's Speed Shop told you to call. He knows me well.

Will post compression numbers soon. Ford recommends revised head part # 2c5z 6049 bab. Supposedly their last revision for cooling issue. I believe the 2005 aviator comes with that head. Also if i need a head gotta do cooling mod. Opinions?

There is no replacement for displacement!

Two of my Fox bodies have a blown 331 stroker and a blown 347 stroker. Fast fun on drag day.

The cure for the whine from the blower is an open exhaust. You can't hear anything else but the exhaust! AND.. when you drive into a parking garage, you set off all of the car alarms.

updated cylinder head

What are the part numbers for the updated cylinder heads? When I had my valve seat fixed by Ford they only did one side. Wondering if I should someday get the other side done.

Check it out- As per ford stealership: verified CEL and runs rough, perform IDS test, retrieved P0171 &P0306. perform compression test cyl 6, 8 low. wet compression test cyl. 6, 8 went up 20 psi. cyl. leakdown test , cyl. 6 exhaust 28 percent. mechanical fuel pressure test 30 psi. NOW THE FUNNY PART- estimate to replace left side head $4674. (SMH) estimate to install reman. engine $7017. (SMH HARDER)customer declined repair. DUH U THINK!!!!
