Salt and water equals rust, UK cars all go this way, It is a little better in Ireland as we have only start using salt. You got the same manifold as me, Mine is blowing when under heavy acceleration so I removed all the nuts again and it is sitting in my car waiting for a new gasket, I used the 2 toyota ring crush gaskets but the manifold does not have space for them as the contact area is flat so I am going to use the gasket that came with the manifold plus RTV to make the seal.

Hi Chris, did you replace the manifold and have you had any NCT issue with emissions? I removed my precats last September and my 2000 MR-S has now just failed emissions at high idle only. Am going to add dipetane and take it for a few long hard drives before the retest within next 3 weeks.

@@Jimdwyer1 I just sold the car yesterday however, the precats are not necessary to pass, use diptane and make sure the engine is nice and hot when you arrive at the center, if it still does not pass then something else is wrong with the car.

Looks like your new manifold will crack in a month or so. If you don't brace the lower end to the engine like the stock one, the flexing it goes through will crack the thin stainless steel fairly quickly. The header you bought doesn't look like it has any lower mount locations for those brackets.

The precats disintegrate because of oil seeping past the piston rings and contaminating the catalytic material. Yours has started. It will get worse. Keep a close eye on your oil levels. I'm yet to see a 1ZZ that hasn't suffered this issue.

Hi Andrew. Did you wrap the manifold after. Do you think it's needed? Also, do you think heat would have helped with removing the manifold nuts?
@andrewsparey697
Жыл бұрын
Nope. I think wrap is a scam. It has an application in keeping heat away from the air filter , but thats not a factor for my car. Wrap will also weaken the welds and make your manifold more brittle so as a default, i am not a fan

Yes . Mines a march 2001 so the cats and piston rings had problems. I think the piston rings were fixed in Dec 01 and cat design by Jan 02. 2003 is the best year as A) there is no chance of old engine and exhaust inventory being used and B) they improved the suspension by then and sit 1” lower
