Tips on things to replace after engine removal

g.scov · 05-31-2010, 10:13 PM

this is how the back of the engine looked when I pulled it. I'm thinking someone before me deleted the EGR, albeit very poorly. Can anyone confirm that these are indeed the EGR holes or is this something else? One way or another something is missing.

Yeah someone already took the egr out. The two ports that have to be blocked off are on the intake where it is blocked off and right by the #6 exhaust port. The other ones don't really matter.

so what all do I need to buy to put it back on?

You need all of the egr and the egr cooler plate for the back of the cyl head. I would just leave it go for now and run premium in it for now.

how exactly does running premium fix the problem?

Running higher octane (running at least 91 octane is recommended for our engines anyway) reduces the chance for detonation, but it's not a replacement for a functioning EGR system.

I only put 91 in the tank annyways! so it dosent matter if its there for me.
