I'm under the impression that they are not the same? '98-'00, '01-'02. I did try swapping MAF's several months ago and it didn't fix anything. The other one is descreened and probably bad itself.

Let me test one from a buddy to verify it is the MAF. If that's the case I'll start looking to pick one up.

I've never heard of the maf being any different unless you have an aftermarket one that's bigger.

Gotcha, thanks. I did see some JET ones, etc., that were specific to 2-3 year ranges. I couldn't find any GM ones on the sites.

Random question... I know carb cleaner is obviously flammable but should it catch fire when spraying it on the engine compartment? lol. I mean, that's a sign of a spark somewhere it shouldn't be, right? The motor wasn't really hot when I sprayed it either...

what are you trying to accomplish??

Are you looking for vacuum leaks?

Vacuum leak check, yes.

Also, one of the PCV or breather hoses that runs from the driver side valve cover to the passenger side (?) valve cover deteriorated. It has come apart completely. I temp. taped it back up. I'm burning a ton of oil. It's blue smoke, and pretty thick. Not Seafoam thick, but it's a fair amount. What do I need to replace this tube, and is this related to the burning oil?

The LS1 can pull a lot of vacuum and they are known for pulling oil vapors through the pcv into the intake. That might explain your #8 spark plug. Check the pcv hose and see if it is really oil soaked.

you should just use a propane torch. just turn the valve and blow a little bit of propane around. it'll do the same as the carb cleaner but wont be dangerous :D

Thanks guys. Propane isn't as much fun as the carb cleaner haha.

The PCV hose is soaked through and gummy, coming off the driver side valve cover. So much so it is sliced and I had to tape it back.

This is the PCV fix I'll be undertaking today I think: http://www.bowlingss.com/Mods/SMH%20...0for%20LS1.mht

any news Rick?

down the cliff..

Another MAF didn't change anything. I think the MAF is just a piece in the puzzle. With the MAF plugged in it's almost instantly a P0300 code. When unplugged, it is gone.

Did you do the PCV fix?

If that hose was brittle and leaking vacuum that could certainly cause a ton of problems.

I did do the PCV fix. Nothing changed.

I'm at the point where I am driving a Ford now... '13 "Gotta Have It" Green... I'm going crazy...

It's kind of nice driving a comfortable, reliable vehicle...

:shock:

Don't worry... I'll be right back into the '98 once I get the bastard fixed. Otherwise, once it warms up, the '01 is getting new head gaskets and will become my DD, along with my bike, 'til the '98 is fixed.

any updates?

Nada. I drove it 30 miles today. It's okay on the highway, idles like it has a cam. I've basically given up for now...

you know i actually just read through this entire thread and it just dawned on me you should check your cam sensor.

hmmmm not a ad idea

Cam and crank sensors are both next. Thanks WSex!

wont be crank sensor or else youd be having problems with it shutting off randomly. cam sensors can do the same thing but its more of a possibility that during that cars life someone screwed it up from having the intake off.

lol also my names not wsex ;)

haha I was thanking him for a PM he sent. I've seen some crank sensor issues on Tech that have problems similar to mine. Have yet to see a cam sensor thread showing the same thing though, but who knows. I'm doing the head gaskets in the '01 a week from this weekend. The '98 is getting back burner status at that point.

PROBLEM FOUND! Check the photos for the work done yesterday... All are cell photos so the quality sucks:

Went to do a compression check:

Then decided to pull the valve covers - passenger side:

My buddy Steve has his old LS1 with 55k miles on it (He has his LS6 now) so we're using his heads, springs, rockers, etc:

We're hoping to have the heads and everything swapped over by Saturday or Sunday at the latest. We ordered all the gaskets needed from GM today. Should be here today or Saturday. I can't wait to get this thing back on the road!
