Coolant resevoir filling up

[WSLN 6]

I have noticed lately that my coolant resevoir is filling up after quarter mile runs. There is also some snapping or popping on the passenger side, but no knock on the directscan. Car runs cool (165).
I replaced the rad cap, but no difference.

It sounds like you are lifting the head(s). See if can see any carbon trails where the heads meet the block when looking from underneath the car. With steel shims and studs, a simple retorque was all that was required.

 

[WSLN 6]

I am using the RJC steel shims and ARP bolts.

My reservoir also fills up after putting a load on the engine. Runs cools if I do not get on it. I have determined that it is a H.G.. I noticed minute traces of an oily substance in the radiator and checked the torque on the heads and yep, 6 of the 8 on the pass side took about a 1/4 turn to re-torque them.

 

[SHADOWII]

I agree....

w/MIB you eould have nothing to lose by retorquing the hds and making another run. There are other possibilities, even the ambient temp outside. We're having a bit of 100+* temps here, so it's not unusual to expect higher operating temps.

You certainly have lifted the head and damaged the head gaskets. Have seen this many times, usually on cars using alchy.

Knock does not have to be seen or recorded on an alchy damage, but massive cylinder pressure, detonation, pre-ignition or some unknown is happening in the combustion chamber?

The tune is off, or the mixture screwed up, as the alchy, which has much less octane than gasoline, displaces the gas? Again, a guess on my part, but I know the damage is real.

I warn my customers not to run more than 18-20 psi on our crap pump gas with alchy. For the ones that get "greedy" with boost, they then gain admission to our "alchy graveyard"!:biggrin:

It doesn't neccesarily means you damaged the gasket unless you can hear it at startup and it continues non-stop after the car is warmed up, retorque heads to 85psi and your problems should be solved, same thing was happening to me with the RJC steel shims and i retorqued to 90psi no more coolant missing or anything at all cars runs a cool 164 at all times.. good luck.

 

[Nick Micale]

If the head lifted, and pressure went into the cooling system, you HAVE damaged the gasket and possibly the head and/or block.

Yes, you can re-torque and the car will be driveable with moderate boost. But with time and boost, it will show its ugly side somewhere in the future.:biggrin:

 

[WSLN 6]

Thanks for the info guys! I will retorque and report back. Hopefully moderate means 30psi or less.....

i have seen this too when using alky. there is nothing like race gas.


well as i see it there is still 93 octane in there. So the 93 thats in there still gets compressed to a level to where is spontaneous combusts under the pressure the alky even tho it has a higher octane masks this issue.

It takes 2.3 times the mount of alky to make the same power of race gas. i know that there is not 2.3 times that amount of alky being sprayed.

This is my opinion on it. Flame suit on!!!!

Nick,you're the first person I've seen say this thank you. You're not guessing,you're right on. I blew apart one set of RJC gaskets and two sets of Felpro. For my third set I chose to use the terribly inadaquate GM gaskets. Eventually they started to make that distinct snapping/ticking noise followed by the popping noise. It was shortly after that when I found out about the recommended torque for the knock sensor. Mine was way too tight so I corrected it. It was then that I realized that I had been trying for two years to supress Knock that didn't exist with alcohol. Then one day I put the throttle to the floor and the popping was gone but I had 11 degres of spark retard. The reason for the retard was that I had blown the hose off my map sensor disabling the alcohol but there was no popping at all. Shure enough,when I hooked the hose back up the alcohol worked but it popped big time. I also realized that the ticking/snapping noise happens when the alcohol initially comes on. I no longer use alcohol And can sfely run 21 lbs of boost with 93 and octain booster. These Gm gaskets are the best you can buy. they haven't come apart and I've never lost any coolant,even when it was popping. Again,the other gaskets were blown apart.

Guess our opinions agree.:biggrin:

Let the "alchy-holics" go do their thing!

The problem is accented with alchy in our area because the crap pump gas is "reformulated" with lots of aromatics and they sell it as 91 octane, and will ping audibily at 12-14 psi with the summer emission blend.

No 93 octane [real] pump gas on the west coast.

Another problem with pump gas is the short "shelf" life. Last I check the oil producers quoted 3 weeks, and after that octane quickly decreases.

 

[WSLN 6]

For what it's worth, our octane here is 94, and the`car hasn't seen over 19psi yet.

I think it depends on the amount of detonation the engine has seen and if the retorques were done with the steel gaskets. Ive had great luck with steel type gaskets and high boost. Detonation will destroy almost any gasket. Maybe not o-ringed coppers but then you will bend all the rods or worse. I have not been able to get the stock type to live in cars going over 124mph consistently. They get trails in the graphite on the intake side. Maybe pinned heads would allow them to be pushed a little further but i havent experimented.

And It's Still Together.....

Chicagoland 93 octane.
23-25 psi always!!
25 degrees 1st and 2nd
23 degrees in third
Turbo Tweak chip:biggrin:
Methanol injected from ALKYCONTROL KIT
Stock Intercooler
Nuff said??
Alky works fine when tuned properly. Race fuel is nice but, last time I got 15 gallons it costed $211! (3-5 gallon drums for my non-alky friends) I just topped off the meth($2)

I know it can be done. but for how long? like the guy posted up above when the alky hose come lose your still puimping in 93 octane.

If something happens with the race gas. there is a tad bit more of insurance.

I have alky on my car and i use to use it but i didn't care for the knock issues before the alky could supress it. so now it's just there to clean the intake tract every now and then.

I only run 15 psi of boost int he street anyhow. the car plays hell tring to hook the tires up now much less at 20-22 psi.


Also guy that are using the alky with a stock style o2 sensor witht eh alky being added to the mix you now ahve 2 diffrent stioch of fuels so by the already bogus o2 milivolts your seeing with the alky it's really making it interesting.

I want to make max-power and still yet have a safe tune. i understand that is a oxy-moron but for me why have to tune 2 fuel systems instead of one.

also for the guys with the alky chips there is a knock ignore limit set in the chips so if the motor is knocking the ecm don't show it on a scan tool. but it's still knocking.......... didn't think about that did ya!


IF the alky was the way to go there would be plenty of tsm and tso cars doing besides the 2 that were in the alky class @ BG.

first of all if you had knock before alky then you already had an issue
second the guy had a hose pop off the map . i think the issue is called ZIP TIES!!!!
third if you have the money to have a tsm and tso you have the money for race gas
as for the alky chips with knock ignore it is for transitional knock some cars get when spraying or if you have false knock i think its called FALSE KNOCK IGNORE
