Anyone ever replace the (2ea) O rings inside the manifold where the MAF inserts? Any tips on replacing them?

Thaddeus

Yes

It's not that hard, if you can get the MAF out it's very straightforward.

It's worth it too. After 20 years mine were brittle, cracked, and sucking air.

Any sealant required to install them?

Normy

Yes, I replaced mine. No sealant is necessary. If you coat the new seals with some sort of lubricant, you'll find it far easier to put all the parts back together properly. WD40 works fine, but any sort of grease or oil will do.

It's been found that these seals make a big difference!

N!
