Damn ALKY pump....
-
Ouch! That blows.... Pun intended.
-
110 & constant PL monitor.
-
Take a look at how much they are inside the chamber
-
Kinda creates a hot spot that far in, doesn't it.
-
My thoughts too even sitting on the block they hang inside and I'm only 20 over on the bore. Jason says it's fine I just wonder about a sharp edge heating up and encouragingly preignition.
-
Larry...do you have a PL log for the run?
-
I use tuner pro and a Genll translator to log data. It went lean WB correction went to max AFRs were 11.8
-
What was the boost pressure?
-
Got it home hit the test button no pump. Rapped the pump a couple times with a hammer away it went. It's already replaced going to throw some 9441s in it and see how it works.
-
but it worked when you primed the pump with the test button before you made the run?
-
Yes it appeared too
-
The new pump works every time I tested it with the prime button and compressed air to check the controller.
-
I wonder if one of those vampire knock sensors systems could kill things in time?
-
Strange...I have found that pumps that have sat with alky in them don't like it after a few weeks, but, if the test function bogs the engine, then it should spray fine immediately after. On the other hand, it may not spray a short time later. I know Julio suggests rebuilding the pump every couple of years which I suspect is a good idea because there is no material that will completely resist methanol over a long period of time.
I don't thinh the hg overhang had anything to do with this one..but, my thinking ain't always right
-
I don't think it had anything to do with it either. These 9441 PT's are egg shaped...and I ran some silly amounts of low gear timing last year...and fairly lean at the traps. Larry...get some VR's...piss on Fel Pro.
-
If the VRs were easier to get I would NAPA used to carry them but they have switched to felpro now...
I'm pretty sure it was the lack of ALKY that took out the gasket. I don't run Julio's system wish I did this is the first issue I have had with this set up the pump is a surflo that I had just replaced I did get a warranty replacement.
My last pump lasted 3 seasons and once they get noisy I replace them. Figure it had a flat spot in the winding or something that caused it to stick. I have a prime switch I use that has two relays to isolate my cooling mist controller. The controller is pretty slick it has a digital boost gauge plus a line of LEDs that show pump duty cycle based on voltage to the pump, 1 knob for turn on point a second for max duty cycle.
When I tested the pump I could hear the relays working but no pump once I did get it to work it seemed fine and I could not duplicate the problem I drained the tank with my test button stopping it several times to see if it would stick but it appeared fine. My local parts store had no issue replacing it just to ensure my piece of mind plus they will give me a break on my new parts they always do regardless of the circumstance.

And now all that black silicone is in your oil pan. Just a heads up.
-
the motor is on a stand getting prepped for new gaskets plus the torque converter is at the shop getting tweaked I wanted to inspect the motor after my mishap make sure it was not damaged bearings look good I flushed it twice with clean oil and a new filter before I pulled it out thankfully it was just water no coolant.

Read this from Kirban's newsletter I got yesterday:
[font=]GM AND VICTOR REINZ BUICK TURBO HEAD GASKETS -[/font]
[font=]GM and Victor Reinz Buick Turbo Regal head gaskets are one in the same. The difference is, the ones they made for GM have the GM part number stamped on them. If you buy a set from GM, you will see the GM part number and somewhere a small “v” stamped in a circle somewhere on the gasket![/font]
[font=]I actually talked to a person who had access to the records and tooling for GM for the 1986-1987 Turbo Regal head gaskets, which GM ordered back in 1985.[/font]
[font=]Victor Reinz made the original head gaskets for the production 1986-1987 Turbo Regals. There are two different part numbers, both will work from Victor Reinz for the 1986-1987 Turbo Regal engines. [/font]For over 20 years Richard Clark has used both numbers with zero issues. He has built several hundred 1986-1987 Turbo engines using the same exact gasket we sell.
[font=]He originally found this information out years ago from his local GM dealer. One format has a small extra hole in the head gasket that actually sits outside the head and does nothing. The other version does not have this extra hole that is not used. Both versions are 100% the same except for the one exterior hole. [/font]Our part number is #7576 and we sell a pair for $54.95 plus shipping. The list price is almost $90 a set.
[font=]The end result is the Victor Reinz head gaskets and GM are exactly the same. The real difference is what price you want to pay for a set of head gaskets.[/font]
[font=]We usually have the version that does not have the extra hole in stock.[/font]
[font=]Either version is getting increasingly difficult to get. Most manufacturers that have GM as a client make the same part, but leave off the GM part number for obvious reasons.[/font]

Last set I got from full throttle, and included all but the valley pan gasket. I got that local from O'Reillys. I believe it was about $90, but that was 07 or so.
