I have done a search on this term many different ways and I still cant find an answer. Do any of you gurus know if toyota fixed the bhg problems with the 89+ (well specifically my year if there is a difference between the 89-92 regarding to recall issues maybe for the head bolts)

any answers would help thanks

No recall was ever issued. I believe the torque spec was eventually increased in the TSRM. Plan on doing the HG at some point if its not already blown in the car.

Welcome to SM. Its good to see another guy from Oregon on here. I live in Clackamas. as far as the ARP's you could try VIP Performance they might have some but your best bet is going to be online.

Man.. you guys crack me up. Just because it has 88,000 miles on it.. does NOT mean the head gasket is gonna blow.. lol. Yep.. its a problem, but who knows what the previous owner has done with it. If your planning on running stock boost, it wouldn't hurt to have a leak down/compression test done to give you an idea of the status of the engine. You can have the headbolts retorqued at the same time if you like, but a GOOD mechanic who understands the car is fairly critical if your not doing it yourself. There is a test to see if the head gasket is leaking as well (I cant remember what its called, but it detects the exhaust gases in the coolant). Plus.. if it was leaking you should see oil floating in the coolant as well. Not sure why everyone jumped on the BHG band wagon.. I have had my engine running for over 4-5 years without a retorque and other than leaking valve stem seals, the engine is very strong as is.

Bad head gasket? Very possible.. perhaps likely.. but not definite. Personally.. I worry more about the quarter panels/wheel wells in the rear and the brake light gaskets. Rust is a bigger problem to me than an engine.

Now.. if your planning on running the car hard or building for a higher rwhp rating.. thats a different story...

^true but my car had the head gasket redone and had a new head put on by Toyota in 2004 and it blew three months ago with only 110,000 miles on the car and engine. My car is N/A and its an auto lol. If I could go back in time re torque my head bolts I would. It would have saved me a lot of money and time. If you plan to keep the engine stock for a while just re torque the head blots to 75 ft lbs and call it good.

Yes, retorquing is a maintenance item on the 7M though that a lot of people tend to forget about.. :)
The best advice to a MKIII owner is... maintain the damn thing properly! If you ever wonder why they are so cheap right now its mostly because the people who really like them are usually very young (at least.. the ones I have found) and are just learning the pitfalls of poor maintenance (which is fairly expensive). Most of the oldsters pass by the MKIII as being impractical and overly expensive. I bought it knowing full well it was going to cost me a fair chunk of change to get to where I wanted it. And.. before you jump on me for the "young" remark.. let me point out.. its a super cheap sports car which is what attracts the younger crowd. The people who kill the car initially are usually not young... :)
From what I have found over the past few years is that most BHG's come from people doing the head gasket themselves. This is not like a typical head that you would redo, the other engines seem to have more leeway on error. For the 7M if you dont have the block and head surfaces lapped correctly (the intial BHG usually corrodes the block and cannot be ignored), it wont matter what you torque it at... it will fail again.

The bulk of MKIII's I go look at as potential purchases are pretty well junked and the owners are usually shocked when I point out where and why (most get a little annoyed.. lol). I would guess one out of 10 (that number may be very high) is worthy of building. My car should have been junked, but I chose to stick it out regardless of cost because I had no other options nearby. I wanted a MKIII, not a MKIV... and mine was the cleanest I could find in the area. (of course.. 20,000.00 later.. Rodel puts his up for sale.. sigh...)
The other interesting chunk of info is, I have found that most people who have no idea what the car is "truly" about end up trying to get rid of it after the first 6 months. Thats generally when they find out how much it costs to redo quarter panels, wheel wells, engines, transmission.. etc.. etc..

The MKIII is 19-25 years old (depending on your year). Consider it an antique.. even though its got the body of a gorgeous woman.. :)
