Hey all. This might be an odd question to ask here but I need some guidance. I recently got my '00 Lincoln LS and how I got it was complicated but at any rate I obtained it for free. It has 230K miles on it and I have been doing some small things (coils, fluids, alt) the cars interior and exterior are in good shape. I now however was told that the Valve on Cly 7 was bent. Dunno how common or whatever but anyway the car still drives fine, just with a small vibration.

So heres where I need help. I met someone who said they would trade a 1988 C4 Corvette for my Lincoln. It has 100K miles on it and it was very nicely taken care of. What would you guys do? Keep the Lincoln and fix it or trade for the vette?
 
I would have a hard time trading anything for a '78- late 90's vette.

That being said, how do you know the valve is bent in #7 cylinder? Did a leak down test show no pressure or???
 
I dunno Bob, wanna call him and see if he still wants to trade his LS ?

Bent valves usually mean the timing chain let go or skipped teeth or something like that at some point on these cars. Never really heard of them just randomly bending valves on their own.

A junkyard head is a couple hundred, plus your labor or shop labor to swap. What is the car worth when fixed vs the cost to repair? What is the Vette worth?

Seems like it boils down to simple math to me.
 
Why would you replace the head for one bent valve?

you think a bend valve does no internal damage ?

not LS specific but just an example,
also, bend valves could crash into the pistons.

easier to pick up a new head from JY with everything all ready to go in.


... but, that's not the OP's problems.

I'm not arguing that a bent valve can cause damage. I'm merely asking why you would replace a head because of a bent valve. If a valve nicked a piston, how would swapping the head help?

[quote="oddball, post: 2037226487"]With a junkyard head, that may be quicker and easier than getting it fixed. Anyone checked to see if there is a supply of valves?[/QUOTE]

Not necessarily. Even with a junkyard head, I'd still want to take it to a shop and have them clean it up and make sure it's in working order before installing it
 
true, true, not to say that it would do that kinda damage and not to say that a JY head shouldn't be send for a cleanup before installing.

However, OP's post off topic, not his current problem unless he comes back with low compression tests on that head.

He states it seems to run fine with a slight vibration.
He didn't mention that it ran like crap and had no balls.

you'd know it if you skipped a tooth and bend valves.
(unless your my wife who just turns the stereo up louder to overcome the noise of a bad bearing, instead of telling me)
 
No but with something like that said, I would have a shop do a compression test on it before I even put down the first coin.
 
i wouldn't take a c4 if it was free, sorry, but personally, they dont interest me at all.

free LS, sure. drive it till the motor sh!ts itself, then replace with a JY motor for as little as possible. then drive it till the next thing breaks. i would continue this process till the cost of repair got too high for it to be worth it, which probably wouldn't take too long before it would just be better off to buy an LS in much better shape with far less wrong.
 
The main issue is that I seem to always have the CEL on for that particular cylinder. Its cly 7 and even after a coil change it still states there is a misfire.

Did you change the spark plug at the same time that you changed the coil?

Does the coil connector latch in? Is the fuel injector connector for #7 latched in as well?

What specific four character codes are you getting?
 
yes give us the codes to see if we can help. i would change the injector first just in case before i changed the heads.

Ill pull the CEL again. Sorry for such a late response, life's been busy. I did both Plug and Coil, everything seemed to "latch" in.
 
Provided the Vette was in good shape I'd swap instantly. 00 LS's are going for what, 3-4 grand with no problems? The Corvette is easily worth 8 grand or more if it isn't trashed. If you would really rather have an LS, you can sell the Vette and find a newer LS without an engine problem for 6 grand and pocket some profit. If you did this and could wait until next spring I'd be willing to part with my 2003 LS, in the Tulsa area, for say 6500 bucks? It doesn't have any problems other than the backup alarm doesn't beep when it's really hot and there's a few paint chips that need to be touched up. What I thought was a trans problem apparently isn't, seems these transmissions don't have the imperceptible shifts I assumed a Lincoln would have.

I do agree with 1LoudLS on the C4s though, I wouldn't own one for personal use.

I was thinking about just flipping the C4.... seeing as it would be just money in my pocket.
