Leak - Possible Intake or Head
I found this forum looking for a DIY for my 5.7 Vortec intake manifold gasket. Found a great one, and liked the caliber of the posts here. Looks like a great and knowledgeable group.
I'm the original owner of a 98 Chevy K1500 suburban, 160K+ miles. Been nursing a leaking radiator for a few weeks. Got hot a couple of times, but not in red zone or boil over. Topped up periodically with H2O. Last week I checked the oil and it was a gruesome mud color and read high on the dipstick. Had the manifold gasket done at the Chevy dealer 100K ago. They advised its something of a maintenance item. At $750 then its a big of a sting.
Changed oil, got a new radiator, being tight for cash tried a little Bar's Head Gasket Fix...to no avail. On running it new oil turned a lighter shade of mud - more yellow than tan. I hope its an intake manifold and not head gasket. Intake manifold is a bit of a challenge, but head gaskets are over my head. At 160k+ the expense of having it done might be better applied to a new crate engine or long block. Looking to keep it stock, but considering a 383 upgrade. Only concern is tranny's ability to take the added torque. Again original with a slight front seal drip.
If you don't feed and shoe the mule she'll quit working.
Glad to find a good web resource for GM trucks.
Puller for harmonic damper??
Harmonic damper...that's the first I've heard of it. Read the Haynes manual (barely useful) and a good link to a step by step dyi.
While not on blocks the burb is sitting still waiting for me to tear into it. Rainy and wet here so will move into garage tomorrow for the start of this project. Nice to work out of my house when things like this go south.
Thanks all for the welcome and encouragement on the intake manifold job. I'll take some happy snaps along the way and post.
