Didn't see your reply 2000gtp. Anywhoo. The damn thing just isn't going in. I'm going to pickup some more jackstands and give it another go. I'll pickup some bandclamps and see if I can get it to hold together.

Thanks again for all the help

 

Is the passenger side pipe distorted from the u-clamps? That may be the reason it is not seating fully over the header collector. I would still try to use a band clamp rather then welding, but if you can't get the pipe seated correctly, it may just fall off again. As for the header touching the k-member, it sounds like your motor mounts may be getting worn out. How many miles are on your engine?

 

I thought it might be the mounts also. I have 130k on the car. I asked the guy if I shoudl get new mounts since we were already at it and he said I didn't need them. How hard is it to swap the mounts? I've done the tranny before just not the engine. Can I just jack up the motor and swap them? Is there a how-to anywhere?

 

Its going to be difficult, it would have been alot easier to do it after removing the old manifolds and before putting in the headers.

 

Great. What's involved? Do I have to take the headers off again?

 

I would think this could be giving you some false knock, which could retard timing.

 

Well I pulled the codes for the car today. Got a multiple engine misfire and a o2 sensor not working. I noticed a flashing SES light. Later this week I'm just going to pull all the wires and re-route some MSD ones. Would excessive knock show up as a trouble code? Or do I need to have a different test for that?

 

I'd almost bet every one of your problems has to do with being too close to the header primaries. Check your 02 harnesses carefully for burns.

 

I think the O2 code was from the rear one that I don't have a sim for yet. I can't figure out how to run these damn wires without getting them too close to the header.

 

zip ties are your friend

 

What is the 02 sensor code? It is not uncommon when you install coated headers, that when you first startup the car, it trashes the 02 sensors. I ended up having to buy a new pair of 02s shortly after doing my header install.

 

The codes were

P0154-O2 sensor Bank II Sensor 1

P0300-Random Multiple cylinder missfire

I don't have a missfire all the time, can't track it down yet. I'm going to fix the exhaust first. I can't really determine anything with the car being this loud. Plus every shop I've been to doesn't have any freaking bandclamps.

 

On another note I gotta replace the timing cover gasket and bothe head gaskets. Damn.[/QUOTE]

What's up with the head gaskets? If you have head gasket issues that could be a major problem. Plug fouling (from coolant) loss of compression, etc. I doubt this is due to a header install and am not quite sure why you feel the head gaskets are bad. I would guess that you have crossed wires, sounds like you have some misfire issues. o2's in the back wil set an MIL but will not effect performance.

 

We thought the head gaskets were bad since the cur is puffing white smoke, smells like coolant, slow loss of coolant, and a little leakage around the heads.

I found a wire that was simply burnt down to the metal core from touching the header. I couldn't see any arcing though at night, I'm guessing because the headers were blocking my view.

I've got a set of MSD 8.5s I can throw on, that are already cut to fit. Although I'm thinking I should just go over the valve covers. This wire (drivers side number 3 from front) is the only one that is giving me trouble. Any ideas? Can't get enough slack to run it anyway other than stock.

 

So I replaced the burnt wire with an MSD one. I didn't do the whole set, didn't have the time. I took a long wire and just ran it over the valve cover so it wouldn't get burnt again.

Start her up, idles fine. I drive for a bit and get another flashing SES light. i check the engine at work, no burnt wires or anything. At idle I get a miss after a few minutes.

Is it possible the plug is just fouled and not firing from the bad wire??? Maybe it's just soaked in fuel? I can't check it at the moment, but what is the correct size socket for the plugs? I need to make a stubby one to swap it.
