Blown Head Gasket

...I thought I left that phrase when I got rid of my Supra..

Anyway, looks like I have a blown head gasket on the GW. Have the milkshake on the oil cap, coolant usage for quite awhile (that I thought was a leak), and now a coolant leak the appears to be coming from the passenger head. I haven't had any overheating issues (max it has seen in my ownership is about 225-230) and that was a few months ago. Any other definitive tests to look into before tearing into it?

Also, is there any head gaskets to stay away from? I was planning on just getting the Fel-pro kit. And what is the opinion on re-using head bolts?

Just "my opinion". If I'm building a fresh motor I go with new bolts. For maint repair work if the bolts aren't stretched or the threads deformed I reuse them. Either way you go you'll still have to re-torque them after a few heating/cooling/running cycles. I usually go with 200 miles and re-torque and check again at about 500 miles. Just my SOP and not chiseled in stone gospel.

Can you get head bolts at a hardware store? If so it wouldn't be more than 30 cents apiece to replace them.

Head bolts at a hdw store for 30 cents at a pop? NO.

Just curious. I've matched small screws for stuff at hardware stores but I guess head bolts are a bigger deal if they all crack and separate on the highway.

Ive read that the felpro 1008 is a good head gasket.

I just bought a waggy with an identical symptom set. I'm thinking mine might be a leaky intake gasket since it never overheats. Check the plugs to see if there's any evidence of coolant getting in any of the cylinders? I don't really know. I'm gonna try the intake gasket this weekend, and start saving for a diesel swap....

The lack of overheating did make me wonder but would a leaky intake gasket lead to the 'milkshake' oil? That was one of my major thoughts on it being BHG or worse.

Possibly could, yes. Leaking antifreeze right into the valley area.

Is the oil milky or just the breather cap on the oil fill tube? The breather cap catches condensation from the atmosphere and will usually look milky in cool temps. Change the oil before you tear into a head job. Coolant leak could be from intake gasket or thermostat housing or water pump, the fan tends to spray coolant around the engine compartment. Just some things to check before pulling the top of your motor apart!

Quick thought- Do the longer water pump bolts need thread sealer?

Update-
I took the longer bolts for the water pump, and accessories off, added thread sealer, and torqued to spec and this seems to have remedied my coolant leak which I thought had confirmed my fears. Took it for a longer drive and no "milkshake" on the oil cap and no notable coolant usage. Thanks for the advice here, probably saved myself quite the headache tearing into it
