Rb26 Plenum Install

[Deziner]

Hey all,

Is it possible to remove and install a stock plenum with the engine in?

I have searched for a tutorial and have not been able to find one.

If it is possible do I need any special tool? I have a polished plenum and gaskets.

Any advice appreciated.

Cheers.

You can do it.

Expect to invent a few swear words.

Hahaha!

It looks like it! LOL

Might be worth also refreshing the hoses / clamps while your in there

[Deziner]

Thanks Richard. May do that.

Glad I wasn't doing it.

Pays to have pint sized little person hands and more patience than a nursing home.......

Unfortunately a lot of photos have been removed from Photobucket but the instructions are still worth the read.

Not that hard

I did my mates one in one avo to fix a coolant leak

Although I've done it afew times so know where all the bolts are and what's needed

If all the coolant hoses are original don't even consider not changing them. They're a ticking timebomb, and this job is a big PITA so you'll hate yourself if you have to do it again.

I would pull the motor out but thats just me. I have extracted so many engines i could probably have the engine out before you even have half the plenum unbolted

Agree, also gives you the opportunity to check out the hot side far more easily.

And replace the hoses around the rear of the head too - those tend to split as well, and that is just as much of a nightmare

Did it over a weekend. Lots of swear words and painful in the end. If you are removing that side for whatever reason make sure you inspect all the hoses like everyone has mentioned as you don't want to have to remove the plenum again due to cracked hoses, lol.

You don't really need a tutorial to do it, you can locate all the bolts required to take the plenum off, but if its your first time will definitely take a bit as there are a few 'hidden' bolts that can be a pain to get at.
