Did the mani swap and had a few problems.I made my own block-off plate out of gavanized alum. and didn't use a gasket and when re-using the egr bolts for the housing one broke in the hole and the other two I can't get tightened down all the way,I'm sure I need shorter bolts or the gasket right?But the only gasket I had was on the housing where the egr bolts to.Started the car up and it was making a loud noise which was where I had the plate but idle was fine and car didn't throw the cel and ets off light until a few min. later.Can I drive the car with the plate not fully sealed?

wow... ok. ok ok ok...

yes, u DEF. need shorter bolts, i did the same exact thing a month ago... broke a bolt off in the head cuz it was bottoming out and i was a dumbass and didnt realize it. i used the GM egr delete plate and a gasket and they were still like 1/4" too long.

i found some really nice alan head style bolts at lowes for it, they even look better then the stock alan's do. they are quite a bit shorter and worked great, but getting that broken bolt out was a BIOTCH lemme tell ya!!!

DO NOT drive that vehicle without the proper parts in place, go to ANY parts store and get the head-to-plate gasket, its like $3. hell, you could have just went to GM and bought the egr delete plate and gasket for under $10.00!!!!

now is the time to send your VCM off to get re-programmed and have the EGayR removed, i did this and my car runs great-no CEL'S no 'trac off" works flawlessly!!

and in all honesty, i wouldnt use that custom plate you made, just go and order the right one for the job, this isnt something you want to risk screwing up, get it done the right way the first time.

i dont have it-no... but all u gotta do is go down to gm and say you need an egr block off plate for any year 2.4 in any car and it will come up, i have no idea what car if any the block off was even used on, the newer 00+ cars dont have the EGR, but they dont use the block off either... they dont need it as their exhuast mani's dont have the 'channel' in the flange to go the lil hole in the head. if you get a 00+ manifold or header you dont even need the block off plate.

i think it looks gaudy w/o it though-even if its not needed i think ppl should use it just to clean up the holes in the head.

now is using only the block off plate bad for exhaust flow, on a pre-00 cars due to the exhaust manifold still trying to flow gas through the head.

so wouldnt getting a 00+ header be better

ok guys just called two Gm dealers and the pn# I got off the ORG.#24575503 which is the block-off plate doesn't even register,they said they don't have it and can't order it,they have the gasket,not in stock,but that's all they said they could get.What now?

update: I called another dealer and they do not have it(plate) and even looked in the GM Performance catalog and do not carry it for 4cyls.I called Hardcore Racing and they have one for a 2.4 supercharged but that's it,I don't know if that'll work.I also tried to take out another egr bolt and THAT one broke off too.Should I just pay to have a plate fabricrated and have it welded on??I'm lost and need this car for this weekend.

^^ did you try asking them to search for a Egr block off plate for a 2.4

www.gmpartsdirect.com

block-off plate part #:24575505

Gasket#:24573947

no worse than having it go through the egr valve i would think... i doubt you would notice any difference by putting a 00+ manifold/header on, but it would be best since your doing away with the system.

biggs: if you cant find one, lemme know... i'll buy one from my dealer for ya as i know for a fact the gasket and plate are $6.00 for me.

you would just have to send me the money and i can send it to ya in an envelope!

Glad to see people doing things the write way!

no prob. man....good luck

Just so you know - I do believe GM came up with the block off plate because midway thru 99 they switched to no EGR but had all these bloody heads cast already so they machined a block off plate rather than tossing the old EGR heads.

Makes sense to me anyway.

As Brad said, block off plate, gasket, shorter bolts and you're golden.

For the EGR, HPTUNERS can eliminate that code for you and you're in business. Contact SHIFTED.

Brad, jump on MSN one day I wanna hear how things are workin' out.
