Possible head gasket between one & three

[fc227]

Greetings all,

Well I believe I have a popped head gasket between 1 & 3 again. Happened on the way home from the track last night. Ran great all night. On the why home it didn’t feel right (bucking ever so slightly) got off the Highway and it was skipping bad, O2 read real low and I could smell the car running rich. I thought well I lost the O2, replaced that and pulled the plugs number one was wet. Replaced them. Started it up a still a skip @ idle Pull the injector plugs one @ time and even though the idle changed when 1 & 3 where pulled. It was not as much as when the 5, 6,4,2 where pulled.

Going to borough the compression tester from work Monday to confirm.

Best way to check for head gasket failure is check the oil. Do you clean oil or a milkshake?
Next check coolant levels if its low you may be sucking water past the gasket.

Compression test never lies either.

Pull the plugs and get a coolant pressure tester. Pump it up and watch for coolant out of spark plug holes. Or do a leakdown test and watch for bubbles in radiator. Compression test can be inconclusive on a headgasket problem.

No bubbles in the radiator and the oil looks fine. thats why I think it's between 1 & 3 . pulling the plug on the injectors on those two holes has less effect than pulling the remaining .

When I popped 1 & 3 was back when I had it in the olds and I ran the tank dry , leaned out BOOM !

No boom this time , But it has the same sound .

Compression test will confirm , Good lord willing it is something else , But it is not looking that way.

 

[fc227]

Just for "giggles" I swapped 1 & 3 plug wire , Made no difference. I did not rev it up , But that is another clue

head gasket

I would think if you suspect between 1 and 3 then the spark plugs would look different at those 2 cylinders?

 

[fc227]

New plugs as of this morning. #1 was wet (fuel) when I removed the old plugs , 3 did not look bad . and the rest did not look bad

The tail pipes have soot , but the BLM's are @ 130 and it is not throwing a code.

 

[fc227]

You know this stinks , It would have been "cooler" to have them blow out (if it is them) at the track instead of on the what home on the highway

I wanted to good to Muscle puzzle next weekend oh pooo

 

[fc227]

Just looking it over again . Hole #1 make no difference if fuel injector is unplug. Hole #3 make some difference (idle drops) But not has much as when the rest are unplugged.

Maybe the injector(s) on one and three are bad, I was pumping out fuel at the track switching from race fuel to pump gas.


Good Lord willing maybe it's not has bad as I am thinking how many cars have the head gaskets good driving down the highway ?

Compression test tomorrow will confirm.

Broken rocker shaft?

 

[fc227]

possible , But it is not making any noise

 

[fc227]

OH POO !

#1 = 60 psi
#3 = 70 psi
#5 = 150 psi

Blown head gasket

OH POO !

Blown head gasket

LOL You just can't seem to catch a break Fred. Sorry about your misfortune there bud.:redface:

 

[fc227]

Seem's like I spend more time under the car then driving it.

Well, I guess I will pull the heads and repair it. If it stops raining here.

 

[fc227]

Are the torque specs 60FP for the heads & 32FP for the intake ?

 

[SHADOWII]

The stock.....

irons recommendation is 60/32. I took my irons to 85#/35#! forgot to mention I have hd studs!

 

[fc227]

Got as far as the intake off and called it a day (found my old pcv grommet :biggrin. I should have taken the "Y" pipe off first ,but..............

Here is a link to the damage

That's what happens when you don't use gaskets for a Turbo Buick V-6. Notice the bridge missing like on the cylinder head. Try the 9441PT felpro gaskets.
