Looking at buying an 89 Mustang that has had some work done. It has a 302 in it with aftermarket heads. the # 3 cylinder exhaust valve is either bent or not sealing. They put air to it and detected a leak. They say it runs ok but has a skip in it.
My problem is I am in New York and need to drive this 700 miles to Indiana.
Does anyone think it would be possible to drive it this far without furhter damage or without doing any repair work to it until I reach Indiana?

get a video of it running.... and running with no driver in the seat to play with the peddle

your not gonna hurt it anymore, and 7 cylinders is no biggie.

it got hurt at high RPM, you'll keep it low on the long haul, like 2500 rpm's

if there is a bent valve, you'd be crazy to drive it that far, cause if by chance the head of the valve breaks off, say goodbye to the motor

i was told it has a 7000 rpm chip in it, it was supposedly over-revved when it hit a slick spot and bent a valve (#3 exhaust valve) could I expect any other damage? it doesn't knock at all . would it need both heads pulled or just the one? it is supposed to have been tricked out with over $6500 worth of parts put in.
the car has 60K on it but the motor has around 11K on it. I can buy it for $3000 as is, it has the 17" cobra rims, little rust around sunroof but dowsn't leak, cowl hood. am i a fool to pass it by?

I would pass it up, but thats just me.

If you want a second look at it, I would double check the usual fox rust spots as well as the torque boxes to make sure there not cracked. If they are, you know the car has been beat on.

If it has $6500 worth of parts, ask for receipts.

Your taking a gamble IMO if you buy this one.

I love when sellers say that or the always popular "the motor is built". As a buyer I want PROOF!! Not what some redneck claims. 9 out 10 times when a seller uses the words "built", "tricked out", "souped up" he is full of $hit and does not know anything. Guys that actually do build up engines know exactly what is in there, can quote the cam specs off the top of their heads, know the compression ratio, head flow numbers etc. Unless the seller can provide proof of what is really in there, for $3000 I would pass.

RUN! 85% likely you will rebuild the engine, or atleast a freshening up! main question is why arent they fixing a simple bent vlv????

there are so many things that could be worng in this case! most of the time over-reving an engine is anything over 6-6500rpm unless you have spent some serious cash on vlv train etc! I have had my last simple 308 at 7500 more than a few times never bent anything!

any givin senerio can result in different things happening and a bent vlv is prolly from vlv float, meaning incorrect vlv springs for the job! (overreving) and not enough ptvc!

someone having a 7000 rpm limit chip should have known the correct parts to keep an engine alive at those rpms!

With there air test how do they know its a vlv? could be rings, could be a cracked piston?????

you dont get your build cost back from a car when you sell it even if it is running great! a limping car is worht half what there asking! almost all the time!

yes yes the coined fraise (built) etc blah blah, yeah every engine is built it just dosent poof itself together!

Every engine i build gets a build sheet for record, for my own or for who i built it for! has everything from simple cuin to ring gaps to endplay measurements!
