bhg .... how much?

duece · 08-26-2005, 09:31 PM

i believe... but have not been confired that i have a bhg on my 1990 supra. my symptoms are.... white smoke from exhaust, discolored oil and running rough and idiling (sp?). these symptom happened after my car overheated and i replaced the radiator. from reading previous forums, i'm assuming this is what my problem is.

do anyone know how much it cost to repair a bhg?

frustrated in NC!

It seems like the price of a head gasket, getting the head milled and other various gaskets are the major things. Hopefully the head will be in good shape when you look at the bottom of it, not eaten up or anything. You might want to replace the valve guide seals and even look into a valve job. Look at the top of the block too, it needs to be flat and not pitted or anything. Then you can look at the cylinders to see if there is any type of ridge at the top of the cylinders. Some is normal, butit would take a micrometer to really tell how much the cylinder might be worn and go from there.

Just my 2 cents

as for bhg i did labor my self in few hrs R&R each way..but one thought on valve job

most machinists around here at least, do not have the tools to get the valves out of the head. there tool wont fit into the valve hole to do valve seals or valve job..and it helps to have a bucket of spare different sized tappets . the round disks used to adjust valve clearences when re-assembling the head. i made many calls to everyone before i finally found a toyota dealer who had a master machanic that was supra junkie willing to help me for cash on his own time at his own pace. he cleaned the carbon out of the valve chambers and buffed the valves and lapped them and replaced my seals and adjusted them all for only 60$ and i know he spent more than 2-3 hrs so i scored bigtime..

and one on surfacing.. do not let your local parts pusher try and surface your head on the table belt sander in back.... this is not a good thing. these need to actually be machined down by a machinist in a milling machine. hahhaha

good luck im guessing 10-12 hrs labor book time.at shop rates plus parts probbly 1000-1500$$ bill at any shop.. plan on a timing belt and id do the water pump also while its apart.. get er done...

i figured it would be close to $1500 to get it done... thanks for the information, at least when i go get it looked at, i'll have an idea of what they should be doing.
