anything below 20psi feels slow, anything above feels like time travel

23psi is happy medium.

I'm trying to figure out why there wasn't any overboost protection turned on...especially since you have a MS and this was your first time boosted.

:facepalm:

I failed to verify if it was or was not enabled. Obviously it wasn't but I can assure you it is now.. Sometimes I'm my own worst enemy.

Three hours of bit banging, hackin-n-crackin' yields bluedouche connectivity on my old ass megasquirt!

Had to build a max232 circuit to convert RS232 to TTL then fight with the damn thing to accept my serial commands to change baud rate, SID, and passcode. Pretty awesome, can't wait to test it out!


Also picked up the HF stethoscope and dug out an old knock sensor. Removed R2 and soldered a 50k ohm pot in place to make sensitivity adjustable. Picked the 50k because there was a 47k there already so an extra 3k+/-20% would be fine. Works pretty well on my test bench, we'll see about in the car. Still waiting on a project case to mount the board along with a new power/volume pot.

Well gang, I'm a little bummed out. Not surprised in the least, definitely bummed out.


Will post pictures later, going to tell a quick story and take a shower & head out for the evening. Tore the block completely down and ran over to my brothers where we welded that perfectly round hole shut using a "plug" I cut with a hole saw out of another blown block using nickle rods on an old Lincoln stick welder. After we finished that up I found a huge crack in the block in the other side around the number 1 crank journal, so I drilled the crack ends and jbwelded it up. Ran a ball hone through the cylinders, took a burr to the crank and cleaned up all the sharp edges, power washed everything and stuck the crank in. Measured the main bearings, they all checked out in spec.

At this point I took the rods/pistons from my original car's engine which were in fantastic shape and cleaned them up really well, checked ring gaps and matched them to cylinders then installed pistons. Checked rod bearings out, they were in spec. Checked crank thrust bearing, in spec. Assembled and torqued everything down, cleaned and installed the oil pump/pickup/windage tray, then another oil pan I drilled/tapped for return. Threw the head and everything else on, set valve timing, belts, alternator, flywheel/clutch, transmission, installed in car. Got it in and cranking in 5 hours start to finish.

Turned over the engine w/out ECU hooked up to build oil pressure, gauge indicated like 10psi at a slow crank so I threw MS in and started. Planned to do the FM "new engine break-in" procedure, warmed it, coolant, got 200 feet away from my house on very gentle acceleration and it started knocking something bad. Aftermarket oil pressure gauged worked while cranking but suddenly didn't work while running. Checked all connections and everything was great. Cranked car with turbo feed line disconnected and a torrent of oil shot out.


Like I said, not surprised but am disappointed. This was going to be the most epic redneck A-Team engine I've ever heard of. Will post pictures later.


Cost to "build" this motor:

Oil: $11.00
Filter: $3.50
Rubber hose: $4.00

$18.50 total. Damn.

:laugh:

you can't be serious

you better provide pictures of all this

this thread is going to go over 9000 if you seriously just tried to jbweld a blown block back together:laugh:

Car stuff is always depressing post pics of the house remodel. A house is also consuming all my car time as well.

The JB weld wasn't really critical, I was more lol'ing over the giant hole we plugged by welding in another piece of cast iron. Neither of those "patches" failed, it started knocking for some reason. I suspect one of the bearings might've been too far off... Used plastigauge after all.

Nice house, man. That's like the perfect size (for me).

Props for engine fang-doodaling.

elesjuan 08-04-2013 09:11 PM

Thanks man. It's for sale.. I'll make you a good deal on it! :D

Braineack 08-05-2013 09:43 AM

wow.

18psi 08-05-2013 09:49 AM

This thread should be stickied:laugh:

Not even faeflora actually attempted jb-welding a blown engine.

tincan 08-05-2013 05:58 PM

Sweet house, looks like it has a cool floor plan. The tile work looks great. All that work just to sell, I know that story.

To be fair, the welded part (and jb weld for that matter) didn't fail. I think the oil pump failed, nothing else explains why it had no pressure after actually running. Didn't break that pump down and scrub / inspect the entire thing before reinstalling, only cleaned with detergent and installed.

What can I say? I'm a jackass and made a great story. Would've been better if it ran without knocking. :rofl:

Kinda sucks pouring all this time and work into the place just to sell, but with the margin of profit I stand to make on just this ONE house I could retire after finding half a dozen more like it.
