Finished!! Forged piston block, Custom valve head (flowbenched)

[Ondonti]

Annoying problems so far that prevent me going out for a drive.

I get the motor running for about 5 seconds, then I hear splash. I turn off the motor. Oops, the machine shop forgot one of the oil galley plugs near the oil pump. I bent an 8mm allen wrench trying to remove a plug from a spare block. Drove to Walmart at 3AM to buy a set of allen head sockets. Removed plug from spare block, then put it in my new motor. I dumped out 1.5 quarts in 5 seconds :P

Then I tried to start her her the very last time, I found Im absolutely retarded and I didnt complete part of my return fuel line so fuel was going everywhere (heard the splash after I let off the starter). Car ran for 10 seconds on a previous start and then died when I let the clutch out (car not in gear so.........).

Also had a massive leak on my fuel feed line. The line I used had pipe fittings on it and they were not night.


My most worrysome problem is that I seem to be getting some oil seepage from where the Oil from the block feeds in to the heads. It is happen on the feed side of each head. All I see is a minor wetness around the headgasket but that bothers me a LOT!

I datalogged the 10 second idle).
When I started the car up, a/f was reading 10.3:1 for the first few seconds that I had it running. Car was pulling 15.8" vacuum. (low compression motor and rings arent seated yet.
The engined died the moment I let the clutch out (not in gear). Not sure if I screwed something up with that switch.


Anyways, I have the engine at ~15 deg timing and it doesnt want to start. @ 20 deg timing it started right up. I pulled it back to see if it would run but apparently it doesnt want to start. Same thing happened with my spirit. When I run open manifolds, I have to run 20 deg of base timing.
Going to bed now. I might not get the car on the road because I wanted to drive it to California this weekend but since I would probably have to spend half of the weekend fixing stuff I will probably just drive the spirit.

back hurts, covered in oil, hair soaked in oil. I totally trashed the driveway with oil and gasoline mix crap. Probably wont work on the car again till next week since it is being such a POS.
I did get all my wideband stuff setup and my datalogging was going. Just pissed me off that I have these stupid problems.

I am very worried about the headgasket though. makes me think I should pull the valve covers and check the head bolts (currently @ 80 ft/lb). Im using an MLS headgasket so it doesnt have all the sticky stuff that the sohc paper headgasket has to hold in liquids.

Did you use the MOPAR MLS sealer on it? If you don't they'll leak like a bastard....had a friend found that out the hard way on a Neon...

[Ondonti]

No I did not.

I guess that means the heads are comming off

I dont know anything at all about the application of MLS sealers.

[Ondonti]

Did some reading and Cometic Gaskets arent supposed to require a sealer.

There is.......
"Additional sealer is not required with Cometic MLS Head Gaskets. The outer layers of the gasket are coated with a .001" thick coating of viton (a high temperature flouroelastomer)."

Whatever that means.

[Reaper1]

Hmm....well, since I don't have direct experience with this I can't say for sure. I CAN say that whenever I do a headgasket on a TD I ALWAYS use copper seal on both sides, even though they also have an adheasive/sealer on them too. I don't think it'd hurt...*shrugs*

[Ntrain2k]

Copper seal FTW!

Did the trick for a tiny little high compression 4 cyl build I did years ago. Couldn't keep a head gasket living on that sucker before that.

[Ondonti]

That pisses me off. Well the stuff on the headgasket doesnt seem to be working.

I just dont want to pull the heads off

Ntrain you talking about your 1.6 honda you overrev'd?

[DustyR/T]

So what did Cometic say about your oil issue? Is it in the design, or what? Is there any other head gasket company that will work w/ the 3.0's??

[Ondonti]

Im not sure whats going on yet.

I was gonna pull the plugs and see if the end cylinders look funny.
Im not sure if the sealant needs to get warm before it really works......I just dont know They say once it gets hot the sealant on the cometic is done.

Somewhere else said to give it a couple heat cycles to seal................ not sure I like this idea.

New problem.

after fixing some fuel line problems, I got to starting the car again. My experience has been that when you run open manifold you need to run a lot of advance. Well apparently with my cams that was a BAD idea. I split my ported plenum with intake backfire. Upper and lower halves separated, and I blew out one of the screws that holds it together.

Oh man.. Too much NAWS! You blew the welds on the intake man!

[Ondonti]

I got pictures of the burn marks but I dont know if they came out well since I havent uploaded them to the computer.

"Warning!!

Danger to intake manifold!!"
