Just a FYI the RemFlex can be had through Napa at least a few up this way were willing to get them.
Wow you'll give me 5k plus deliver? I just couldn't take advantage of you that way

yea i wouldn't feel right takin yur $$ just to deliver it

BTW - it was running 17.33 in the 1/4 (with a POS carb even!!)
it hauls tons of crap at 70+ on the highway
it corners like a BMW
and tons of people I have no idea about give it the thumbs up or holler at me to let me know it's an awesome rig

oh yeah - and Captain Kirk went from the Captain of the Enterprise to riding around in the back of it doing commercials!!!

guess i will have to bill you a little more!!!

Exhaust manifold is warped. I see a broken rear stud coming soon (yes, that's why they have a tendency to break). While you have the head off put some new high quality ones in with zero fatigue life.

Consider taking the intake/exhaust manifold assembly into a machine shop to get it surfaced as a unit. That can probably wait until you have more money but spend the few bucks on the studs -- at least the rearmost one.

Wild guess is that lack of careful periodic patterned retorquing of the head bolts (I forget what the schedule is for a new gasket) is behind the gasket failure and will prevent a new occurance. Witness marks indicate a higher loading of the inner bolts.

Looks like you need new valve stem seals (#3).

Be careful with long sanding blocks. Make damn sure they are flat over their entire length or you will introduce distortion rather than remove it. Also keep in mind that rigid bodies are theoretical constructs. When you have a long flat bar it is probably flexing as you use it if you press down more in one area. This seems very technique sensitive for a novice. Kinda like jumping into the art of finishing optical flats.

Sorry to hear about your back.

It does sound like him.

how did this happen, #6 looks like a lean mix lite the fire ring in the gasket and blew it out when it weakened,also the ex side of the manifold gasket seems to be leaking all over the place, #3 comp chamber looks like high temps cleaned off the carbon layer on the surface.

wow - thanks for telling me what you see from the pics!!

okay - the studs were all brand new 5 yrs ago - actually everything was brand new
I retorqued the head a couple of times - center out etc

i have let it slide for the last 2 yrs though - just checked the valves

i have been running mobil1 exclusively

what I find weird - #3 is the one with all the crap on it!
#6 has a little on it as does #1 - #3 being the worst of them - except that it is also the one that cleaned up quickest - all except #3 exhaust are white - nothing actually on them??

I checked the block and head with one of my aluminum levels - both are straight - the intake/exhaust are too - dirty with crap on them - but straight across - have not taken them apart as they did not leak where they connect - which is always a pain

so what I am hearing is that even after 5 years - it should be retorqued regularly? I figured a couple 3 4 times during the first two years was enough??

as far as leaking all over??
did not see any of that??
only actual spot that looked leaking to me was where it blew through #6 into the galley - what am I missing

anyway - thanks guys

In a couple of the pics corrosion can be seen inside the coolant passages of the block (rear) but the antifreeze looks fresh -- doesn't jive. It could be that your high rpm usage has swept up deep corrosion and deposited it there. At the least the cooling there is not going to be as efficient -- more stress on the gasket. That also means you should look at your radiator to see if it is clogged in some areas.

More "chemicals for better living" are in your future (power flush?).

Nope, but if I were going to be putting this much effort into a head, I would use the revised combustion chamber head, if possible. I don't know if the rebuild on your head included hardened seats or not. If it did, then you are fine.

Kevin - is this the spot you are refering to? - if so, that is a little rust colored but it has nothing in it that moves or scrapes off etc. As a matter of fact, I can even see the casting rod in the head and move it around.

I have stuck my fingers into those holes and tried seeing if anything was loose and my finger comes out clean, not even any rust color comes off onto my finger if I scrape it.

The camera just doesn't do it any justice.

- here is the block with the sanding done.

and the head with sanding done -

All I had to do was use some 600 grit wet/dry and it took me less than 45 minutes between the head and the block - and again, I checked the "levelness" of both by using two different levels that I have - straight and aluminum.

I had the radiator cored and cleaned a couple of years ago and then swapped it in. I have 3 others waiting around to have redone if and when I need them.

I run around in the land of the californicator and this van runs around all over the place in 100+ heat all the time - have never had it overheat - it will get a little warm if I am running down the freeway at 70+mph - but if I take the 55mph roads it never moves from normal.

Anyway, hope this explains that a little more??
Thanks for the thoughts and suggestions?
Dan

Yes, that's it. I was comparing the corrosion in there to the lack of corrosion in the corresponding holes in the head. That made me think the head was hot tanked but not the block (?). Keeping the anti-freeze maintained acts a bit like a time capsule since the rebuild.




I am thinking "why swap in the new radiator?" two years ago. {Rebuild was 5 years ago?)} Did it overheat (you say no below)? The head gasket condition (not failed yet then) could be an artifact of that event (lasted another two years).

It never actually overheated - but since summer was coming on I wanted to make sure - so I switched rads. Was back during a time when I had the $ to get it done.

The block and the head were both tanked - the head was also magnafluxed (?) if that is the term I am thinking of.

Well, thanks guys - NAPA will have the gaskets Tuesday. Can't wait 2 weeks for the intake/exhaust ones from the other outfit (not to mention the $) - so gonna have to use the FelPro's from NAPA -

The head does not need to be retorqued periodically -- that is yet another bit of spurious misinformation by an individual who is not welcome on this board, has already been banned once, and will shortly be banned again. Pay attention to the good advice you're getting from knowledgeable people who actually own slant-6s, and disregard the babble and handwaving from those who seek only to stir up ѕhit.

Thank you Sir!

I am still going to need a carb to replace this pos
Hopefully I will have the wearwithall to afford something next month

As if I haven't had a hard enough time doing all this with a bad back - yesterday I ended up walking out the door and walked off the step and sprained/snapped extreme;y loudly - my left ankle!!!!
Swollen about two times it's norma; size!

oh well - that's life in the fast lane for ya!!

Later,
Dan
