Call them up, that'll let you know if they are still there The have a sister site that does import parts also importperformanceparts.net . Haven't dealt w/ them but looks like a good site.

 

on ebay rite now theres a 2 bbl setup for 200.

 

valve stem seals is what your talking about ( i think).

 

sorry i haven't posted in so long but...

i've got some bad news for the poor slant 6

the head is cracked in a few places :bawl:

However, someone has a slant6 they rebuilt a couple years ago that they're selling for $250 so i think i'm gonna do that... now to sell some stuff.

I'll try to get some pics soon

 

the head is cracked in a few places

Was the engine overheated at some time? Not sure that is the norm for the 225.

 

i think it was like that the whole time i've had the truck... i've always had to put oil in it at least once every couple weeks. (and like, a quart or 2) and replace spark plugs often. i'm sure i could put it back together and it still run but i'm sure i'd be better off replacing it... unless someone could "sleeve" the cylender walls or w/e its called for less than $250 (cost of another motor). don't think that'd fix the problem for good though (or would it)? and what's the normal temp of the engine normally? it usually ran at about 190F. there was one time it got off the scale but that was very brief. and other times when it got around 220-240 due to a hole in a hose (at highway speeds the pressure was high enough it forced coolant out the hole), which i fixed.

there's 3 cracks, 2 are "hair line" and not as long, one is maybe the thickness of paper.

btw the thickest one is between the spots where the 2 worst looking sparkplugs would be when i change them and the other 2 cracks are where the "in between" (not as bad as the worst, but not as good as the better ones, in the mid. somewhere) looking sparkplugs would be so i think this has been a problem for a while and not just seals.

i recall once that when we took off the manifolds one of the studs was a reg. bolt. when we took this out coolant poured out of the hole in the block... guessing it had something to do with a crack in the head?

oh we also found a round looking dome like washer INSIDE the block, when it should have been up near the lifters (i think). of course it was smashed into 3 or 4 pieces. i think someone has tried to work in the engine before... and messed up somewhere

we also had to cut the timing chain just to get the harmonic balance off, a puller (3 diff ones) just wouldn't do it.

sooo, with all of that considered... i guess that explains my 11mpg and the engine "having its moments" with power, and after saying that... i'm surprised how well it did run with all those problems... i'm sure it would still at least run if i put it back together but not at its best and probably not for too much longer

also would explain the "knocking"...probably just the reg. ol sound of the piston seeping through the bigger crack that normally isn't heard as much when there is no crack?

 

what you have posted confirms that the slant six engine is
as tough as an old army boot

i swear those things will run with no oil in them

 

they almost run without oil... the '85 D250 that i sold my neighbor went a few miles without oil before he blew it up. but he beat the hell out of it.

 

i miss my truck...

I'm tempted to just cut my losses and put the engine back together and run it even with the cracks lol
