You'll also need a new by pass hose, antifreeze, oil and filter and some RTV for the corners where the rubber gaskets meet the fiber gaskets on the side.

 

Thermostat wouldn't hurt either.

 

Cool, thanks for the info!

What temp t-stat do you guys use? Ive been trying to decide between the 160 and 180, because the one i have now (OE im guessing) runs too hot for my liking


I havent checked my plenum plate yet to see if its even leaking, but i bought the kit anyways because she ate 2qts in about 4500 miles and my gas mileage sucks (13mpg 80%hwy @ 60-65mph) so im assuming my pre-cat o2 is fouled out, i plan on replacing the PCV too.

 

The 160* will be too cold and you'll probably get a code about taking too long for the engine to warm up. I've been running the same top of the line NAPA 180* stainless steel stat for 8 years and it's still working perfectly.

 

I just finished reading this thread&I do burn a little bit of oil but I just noticed the valve cover os leaking&maybe the intake for there is a spot of oil on the block by h20 pump.Ill relpace vc gasket&then see.Anyway Don't think I have spark knock but I have tinnitus so I cant hear much.Im not throwing any codes,but figured Id look in the throttle body while I was there.Now I looked in the pic thread fir the plenum but mine looked pretty clean but it did appear to be a drop or 2 of oil so what do you think?Heres a few pix but they kinda suck

 

That second pic tells the story of what the inside of the intake manifold should look like when you have a blown belly pan gasket. Sorry but it's time for the fix.

 

Yeah when I saw it I was hoping I wouldnt have to but I kinda Knew it.Well atleast I know where my mpgs disappeared to.Im wondering if this is also why my hvac has been acting funny?I cant seem to find a vacuum leak anywhere.Well off to watch the youtube vids on it.

 

Ordered my ebay plate just now!!! Getting the Felpro gasket kit too and ordering the manifold bolts tomorrow from dealer! pumped!

 

Did my plenum repair last week (along with the water pump, timing set, t-stat, and distributor). I bought the plate off eBay and used the plate bolts that came with it; bought a Fel-Pro gasket set, and went to the dealer for new plenum bolts. Runs fine, now I just have to get rid of a finicky air pocket that's making it overheat...

 

Yeah, these trucks are a real bear to get all the air out......
