bent intake valve?......... HELP!

ok so the motor is in piece's and thought i had a problem with my timing chain, but come to find out my number 5 cylinder rocker arm came free and was bouncing around under my valve cover. so i am at a cross road, i need to to a valve job but is it worth it. Should i do the PI swap, and what would i need. Im not exactly a newbie but just never dealt with a valve job before. what are my options and how much can i look forward to spending. this is a second vehicle so i can keep garaged and work on it so if anyone can throw some idea's at me that would be great!!!::headbang:

If you have to have the heads off anyway... heck yes, do a PI swap.

yeah your halfway there. it would probably not be that much more to do the swap than to repair the current heads anyways.

A PI headswap would probably cost about the same as doing a good valve job on the heads you have. One thing though, how many miles does your car have? If you are at a high mileage, then the increased compression ratio could kill your bottom end pretty quick, so in that case you might want to do a complete PI motor swap.

The only downside to doing the PI swap is you have a 95. I just did one, and for the same reason, but I had the #5, 6, 7, 8 Exhaust valves bent! Same thing, cam followers rolling around in the valve cover. I did the PI swap but I have a 97. For you to do a PI swap you need new heads, intake, upper intake, TB, EGR system, Fuel rails, etc. As has been said, depending on how many miles you've got it might be better just to find a complete PI motor and swap it in.

headswap! Pull some good looking ones from a junkyard and send them to be machined, should cost you about as much as buying one head new from ford. Just my $0.02..... by the way on an unrelated note, how are you liking your swap traveler?

you have the "leaky valve" F4 heads just get some good used F5 heads from the junkyard and there a direct replacement. It will be so much cheaper then trying to fix the current heads...and the F5 does have revised ports, better valve seals...

if you need a pair of heads off 96 let me know. high mileage but in good condition. come to midland or saginaw for pickup and it's free to you.

Thats probably the best advice. Use 96-97 style heads. They are a direct replacement (as has been noted) so you won't have to change intakes, etc. They are relatively inexpensive and they are better heads than what you have now.

About my headswap... I love it. It took some work (Mostly fixing my own mistakes) but in the end, they're great. I'm finally in the 14's, and the car is a joy to drive on the highway.

i have a superchip in the car now, if i come get those new heads will my chip need to be reflashed? The car right now has 190 on it and has a new trans with only about 30K on it (was brand new)

You won't need a reflash for 96 heads. For PI heads, it would be reccomended to get the chip reflashed. Also with 190K on the motor, I would reccomend either sticking with the 96 heads, or getting a complete motor. PI heads would probably break something in the bottom end pretty quickly at that mileage.

so the 96 style head are direct replacement and would go in just like my old ones came out. Also would that give me any more power out of the motor? Are there any different size bolts i would need or anything of that nature?

Yep, what he said. 96 Heads, with PI cams. (errr...... I happen to have a couple sets of PI cams for sale.... ;) ) No reflash required, and they'll "..go on just like the old ones came off."

where in michigan are you at?

i do have a pair of pi cams sitting around but not yet decided to sell it. i might sell it or i might keep it as spare.

the head if you willing to drive then it's yours. if you want the rusty block too feel free.

let me know.

also since the head is out i would recommend changing out the valve seal to a new one since it's cheap anyway.

i live in brighton and do you have both heads or just the one and by the way how much would you let go of the pi cams for? if i did get both heads and the pi cams would i need all new springs, lifters, pushrods, and roller rockers?

i have both head and have the tools to change out the valve stem seal if you want and i can do it for you before you leave. i have a set of springs from the pi engine so you are set. the pi cams i have no idea yet if i wanna sell it and at what price i'm gonna sell it for yet too.

if i'm not wrong pi and npi cams using the same set of valve spring but maybe need some double check. also before bolting in the new head better to send to machine shop to check for straigthness of the mounting surface just for insurance and it would cost much.

with the headgasket and labor and miscellaneous cost associated it might be about the same as putting in a pi engine for just a little more money.

instead of the explorer block i know a place that have iron block pi engine from crown vic and grand marquis for about 600-800 a piece and they mention they always had few of those on hand at anytime.

but if you decided to just get the head from me just let me know and come pick up within this 2 weeks because i'll be leaving the country for 2 months and be back in next january.

let me know.

The PI and the NPI use the same springs. At least I know of many many people who do the cam swap using the same springs.

If you decide not to sell your cams, I have a set for sale (actually two sets - 1 set Windsor, and 1 set romeo)
