head gaskets again!
I replaced headgaskets back in '06 at 100000 miles. Now my '94 4runner has 141000 miles. I noticed that temp gauge takes a while to show a reading. A week later radiator was half empty. I know that I have about 2-3 weeks to go before oil and coolant will start mixing again.
So this is a third time it blew up. Dealer fixed it once at 60k, I did it in '06 and now again. Something is telling me that even if I do fix it now I'll be doing again after 40-50k miles. Please tell me I'm wrong!
Thanks

Those are such a PITA. I would buy new heads, that's what I did in my 88 however I parted it out instead of fixing it.

I beg your pardon, that doesn't make sense. Did you part it out after you bought the new heads?

Maybe you should invest in some headers this time around, 6cyliners. You'll pull the heat away from that back corner where the gasket usually fries, and you'll get a nice boost in power for the effort. That way you can consider the money spent as an investment, instead of merely an expensive repair.

I concur, headers are the way to go. That way you ditch the crossover pipe. Your heads will like the heat reduction that's for sure

I third that on headers it seems like most 3.0l head gaskets go out on driver side near cross over!!!!! I know thats where mine blew out as well. If you do redo the heads at least put a better heat shield around the cross over.

I didn't feel like doing the same thing over again. That was the problem I had with that engine. The HG will blow again eventually even if you do fix it right. It wasn't worth it to me on a POS 4runner, I'd rather fix one that was a nice vehicle to begin with. I made more money parting it out than I had into the whole vehicle anyways.

Last time I had the heads redone and check block with straight edge. Headgasket came from enginebuilder(sp?) Ted I believe. This time I was kinda pissed. So, I oredered a cheapest set from ebay with headbolts and slapped it back together. Hoping to get 2 more years out of it while looking for another core to rebuilt or ls 5.3 swap.

my 3.slo is at 318k and last time I had the HG replaced was more than 100k-150k miles ago... Check your block, the heads themselves, and if there's additional heat going to the HG's for possible leaks or anything of the sort.
