Pi headswap, underway.

brightwhite98GT · May 14, 2008

Found the whistle. Fixed that. Fixed the idle problem. Fixed the knocking problem. Fixed all the problems but the most important one. cylinder 7 was ticking. Then my dad fired it up earlier today to see the problems I fixed on it last night. All you heard was a weird ass noise, then the engine quit, and is locked up. :wall: :wall: :wall: :wall: :wall: :wall: :wall: It was idling about 900-1100rpm when it locked. Im PRAYING and wishing soo hard right now nothing catastrophic has happened. I hope everything will be okay if I can fix that fucking valve. Im pulling it apart now. Please show me some light.

Willis_98GT · May 14, 2008

holy shit dude... i'm not trying to flame you or call you stupid. but did you have oil in it?

and was everything torqued to correct specs?

brightwhite98GT · May 14, 2008

I put 6 and a half quarts of oil in. Just because it says 6 in the manual, I added the half just because everything was taken apart and yeah. There was oil in it. Please tell me my motor isnt fucked! Im ripping it all apart now to see the damage.

brightwhite98GT · May 14, 2008

Im hoping this is good news. Motor isn't locked up. it was just the valves. I can twist the crank until it hits that valve again. Then it gets stuck. Please tell me its possible to have it up and running by next Thursday! Otherwise, I don't graduate school.

find a machine shop that will be able to fix the heads a few days before thurs. since it was the valves hitting the piston, i would assume that the vavles are toast, so they will have to be replaced. if there is any major damage to the engine, chances are its gonna be a bent rod. best way i can say to check it is once the heads are off, rotate the block and see if all the pistons go up to the same level. if the ones that were hitting the valves fall short of the rest, then you have a bent rod and will need to replace those rods that are bent. a good valve job for the heads shouldnt take too long but it just depends on the workload of the shop where you take it to.

most important part of this will be figuring out why you have PTV contact, because the last thing you wanna do is repeat what just happened. are you sure the cams were on the proper side of the engine? are you sure it was timed correctly? and one more thing, just because the manual says 6 qts of oil doesnt mean its gonna be around there. when i do my oil changes, if i let it sit for about 10 minutes draining, i need about 6 qts. if i let it sit for an hour draining, it needs 7.

Will the valves out of my NPI fit the PI heads? If so, Fastlane will more then likely do it for me for free, or in exchange for my help around the shop. They will probably be able to do it the same day. I appreciate the heads up on the oil level.

i think the exhaust valves might be the same size, but not 100% sure on that one. i know for a fact that the intake valves are different size, so those wont work.

brightwhite98GT · May 16, 2008

I am going up there today with the heads. They will know, I'll let you know too for future reference.

MustangMatt96GT · May 16, 2008

I bet the cams were not timed properly. Pm for my number and you can call me when you aretiming the cams again if you would like. Good luck

Wow. i dont know any other way to describe how pissed I am. None. I took the head off, and cylenders 5,7,8 all checked out good. No marks where the valve was touching, nothing. Piston 6 however, shows where the valve was hitting it, but wait, it gets better. the valve was beat into the piston, and the piston is shattered. But thats not it. The rods also bent, because the piston wont reach the top of the cylender. Im assuming the crank is trash to. Pissed? MUCH. The timing was right. I had it checked out several times. The heads were not. The guy cut me a deal on them, or so he said. Since I needed them so bad. And he wont answer the phone. Ive called several times, and emailed him. He obviously already knows. Wow. Now I get to stare at my mustang breathless, in the garage, for the next few months while I save up for new shit. I got two jobs lined up for this summer. So I guess I'll work two. Maybe by the end of summer, I can get some forged rods, forged pistons, cobra crank, p&p the heads, new valve train with stiffer springs, etc.

reivaxtorres · May 16, 2008

sh!t dude, that sucks. i feel for ya

brightwhite98GT · May 16, 2008

I heard from somewhere the teskid block would work with the SOHC stuff. Is this true? If it is, I found one that has pistons, rods, oil pan, and the water pump (34k miles on it) for $500.

MustangMatt96GT · May 16, 2008

Yep. Infact thats a great deal. that teksid is worth quite a bit. exactly what im looking for. Let me know if you dont buy and i may be interested.

you should find 2 more so i can buy one and matt can buy one.

brightwhite98GT · May 18, 2008

Well, Im not getting it. If you want the guys contact info, PM me asap. He is selling the pistons, rods, oil pan, and water pump with it for $500 flat, or just the block for $400, I believe it has like 30,000 miles on it. But yeah, I went up to Fastlane yesterday afternoon. Talked with Melvin, let him know what happened. He gave me a set of pistons and rods laying around that he didn't need :thumb:. Im also giving them that driver side head, and they are gonna see what they can do for me as far as repairing it, or getting it repaired. Fastlane motorsports are the nicest people around, they really know their stuff too. So things aren't looking half as bad as they were :thumb: I just REALLY appreciate what they do for me. They ALWAYS help me out all the time.

reivaxtorres · May 18, 2008

$500 for a teskid shortblock? must be off a mark viii. thats an awesome deal for it either wayt ho.

brightwhite98GT · May 19, 2008

Anyone have a write up on how to replace the piston and rod? Is it difficult?

96gt226410 · May 19, 2008

The guys at Fastlane are awesome. They tuned my car after my PI swap. As far as replacing rods and pistons... You're really deep into it now, and if your head isn't able to be fixed you're really screwed. Why don't you wait to hear about the head before you do anything else. It'll cost you money to get the pistons and rods balanced that you may not need to spend. If I were you I'd start looking around Craigslist for a complete PI engine. This way you'll have less complications.

brightwhite98GT · May 21, 2008

They are awesome. They work magic when it comes to fixing stuff. Im sure they will be able to repair the head for me. As far as pistons and rods go, only number 6 really needs to be replaced (both piston and rod). You guys really thing I will have to get everything rebalanced just by replacing the one piston and rod? Can anyone shed light on replacing pistons and rods?

It wasn't balanced when it left Dearborn. There's no light to shed dude, pull the oil pan,. unbolt the rod, shove it out the top. then rent a ring compressor, and beat the new one in, bolt the rod back on.
