You could probably sell your old cat too, cat recyclers seem to be paying good money for them to recycle the platinum...

Intake R&R runs about six hours book time..... so, multiply that by whatever the labor rate is, plus another hundred bucks or so for parts/oil change..... heck of a lot cheaper if you can do it yourself.

I have purchased the Hughes Plenum repair kit. It should arrive today UPS. I'll install on Saturday and report back to let you know how difficult the repair is.

When you say pull the O2 sensor... Are you saying I can take it out and drive to see if there's a difference? No harm to engine or anything? Just want to confirm.

I just did plenum, kegger and throttle body mod, timing set, waterpump, belts, hoses, tune up. It pulls harder at higher rpms but low end still bogs! Argh!

I have new valve cover pcv - I was going to wait until rockers are done but sounds like I should do now?

ENDISNEAR, How much are looking to sell the remote fuel filter for, and why are you selling it?

To all, I have removed the intake, and found four blown points in the plenum gasket. There was also a great deal of oil pooling inside the intake. I have attached a photo of this. Also, I have a broken bolt on the first bolt on the drivers side head. Not good. I put the project on hold until tonight. I needed to come into work to grab the correct type of bolt extractor (easy out) and tap. I'll let you know how the rest goes. A big tip to guys looking to do this. Take the time to pull the water pump off, fan shroud and fan. If you're a big guy like me you can then climb into the span between the radiator and your engine to clean all of the intake gasket material off. This is much better than leaning your way into the engine compartment for hours on end.
