May 23, 201015 yr So i have a 87 gl wagon. My valve stem seals were bad so i bought a 87 xt motor being told it was a direct replacement. Well now i pulled my intake off of the carbed wagon and went to bolt it to the xt motor and the intake ports are different. There a duel intake head so i was wondering if there is a duel intake carb manilfold? if not then someone buy it cause its getting scrapped
May 24, 201015 yr Nope - you will have to swap the heads. Why are you swapping out motors because of valve stem seals That's lame. Just fix the seals :-\ GD
May 24, 201015 yr Author The local machine shope quoted me $300 just to re surface the heads and pressure check them. I think that kinda alot since thats not much less than what i payed for the car.
May 24, 201015 yr The local machine shop is WAY out of line. 1. Going rate is $35 per head for a surface grind. 2. Pressure testing is not reccomended or needed with your engine, symptoms, etc. These heads rarely crack and there would be no reason to suspect a crack given your intention is to remove the heads to replace the stem seals. 3. There is no need to even remove the heads for a valve stem seal change. You get an adaptor to run compressed air into the cylinders, remove the springs, replace the seals and re-install the springs.
