Do you have access to a block tester? takes only seconds to tell if you have a head gasket problem.

 

[alotahp92gt]

i dont know


check the fan and see if it is woking right


replace your water pump and flush your coolent system

 

[427' Cobra]

no i don't have a block tester but i am goin to buy a a comperssion gauge today and check the comperssion

 

[LEE93COBRA]

check your timing.

Is water blowing out of the reservoir?

Stuck thermostat? Bad HG? Lots of stuff to check out.

 

[427' Cobra]

thermostat is new but when i turn the car off i can hear it sizzling in the passenger side head before it gets to the water pump so that is why i think it is a head gasket any one else think the same

 

[03BlownSnake]

thats why I said you should do a block test... It can tell you right away if you have a head gasket issue. I bet you can pick 1 up like at autozone or something. I doubt it cost more then $30 to buy

 

[427' Cobra]

is that another name for comperssion gauge

 

[427' Cobra]

and it runs on 7 cylinders

 

[03BlownSnake]

no. a block test is basically a test used by placing a special liquid in a container and "sniffs" through your radiator cap if any CO's (I think its that, maybe Im wrong)... Most of them are blue liquids, when you use it and it turns a yellowish color it means you have a blown head gasket. I dont know how to describe it excactly.. does it make sense? Its not a hard test by no means, anyone can do it.

 

[427' Cobra]

ok thanks when i go to autozone or whichever do i ask for a block test kit or something sorry i'm asking so many ?'s but i just want to get it right before i do anything

 

[03BlownSnake]

you should be able to walk into a autozone or pepboys and ask for a block tester, they should know. It has nothing to do with a guage, so if the try selling you something with a mechanical/dial type gauge, thats not what you want

 

[427' Cobra]

i went today and got the block test but i did not do it yet i just got done doing a dry comperssion test and i got 2 cylinders one on each side that are at 130 and the rest are at 140 and one of the spark plugs that read 130 look wet fouled

 

[427' Cobra]

ttt

 

[LEE93COBRA]

have you verified that your getting fire to the cylinders that had wet plugs. Which cylinders are they?

 

[427' Cobra]

i just got done taking the motor apart it's not even a roller rocker motor somewhere along the line some on changed this motor i am putting new head gaskets in it and having the heads rebuilt

 

[LEE93COBRA]

was it suppose to have roller rockers?

The way you described it, I thought it was just a 93 5.0 which wouldn't have roller rockers.

 

[427' Cobra]

opps i mean't to say roller tappets it doesn't have roller tappets and the firing order is this 1,5,4,2,6,3,7,8 does any one know what this motor could be i mean what year it could be well any ways i just order a new edelbrock intake manifold and next wek i am going to get a carb and distributor yes i am goin to a carb motor because when i bought this car (1 week ago) the car ran like shit and the fuel injection system was a piece os shit i don't know what this guy did but i'm just goin to make it easier and go to carb but thanks everyone for ur help
