- 94 XLT 4x4 Exploder
So I got sick of the morning misfire--and a minute amount of anti freeze it was using. I have a very clean 94 4x4 XLT. It was towed to the shop.
Heads came off. #4 was wet. Headgasket.
Heads were taken to a very good machine shop that has built my motors for years, including a 16V GLI 2L in a 89 Jetta that is SCCA Sedan Class raced. 7000 rpm all day long, 10 years later it still is holding together. That engine is beat to hell and back and it still is holding together.
So the shop said one head has a noticeable crack between the EX and IT valve. He said JUNK. He told me if he put a hardened seat in there it more than likely very soon pop the seat and the crack expands. He also showed me where the exhaust valves were pounding the heads.
1-3-5 head looks from a visual chk not to have any cracks. He said he would chk it tomorrow.
I have a 93 4.0 77k motor I bought as a long block over the summer.
I took the used motor to the shop, told the kids to pull the heads on the 77k motor, chk for visusal cracks, then yank the shortblock out of the Exploder.
Machine shop showed me at least a dozen of these heads over in the corner. All cracked. He said ITC is a Chinese aftermarket bare block head that he has had decent experience with.
ASSUMING: All the 4 heads are crapola. ITC can get me bare new early style heads for about $200 each. My machine shop said he would assemble them. O'Reiley quoted $1050 for two rebuilt heads....
Since the 94 XLT is a keeper, I am leaning towards new heads on the low mile block.
IF---the heads on the low mile engine do not show cracks between the valves, should I risk them?
or buy new heads. Anyone wish to spin the bottle with me? ITC going to be OK heads? Seems everyone and their brother on-line are selling those Chinese heads.
