squeaking noise and diagram

[Schmitt20]

Does anyone know what could be making a squeaking noise for about 5 seconds after the motor is running. Also i need a diagram on how to wire temp. and pressure guages.

[Vern Houseman]

is the guage elec or mechanical ?  are you sure nois commen from carbs ? sometimes when you starte your motor and the noise comes from top of motor  mean your head gasket is or has blown out.

[Schmitt20]

it's electric. and the noise is coming from over by the valvecover

[Vern Houseman]

on a electrical guage you will have to run a wire to the sending unite on the motor or on the radiator depending where you want it then there w8ill be a ground wire and a third wire for power , will double check when I get home tonite. as fare as the nois by the valve cover kinda sound like a head gasket to me maybe run a compression check.?

[Schmitt20]

alright. Once it's warm its fine. So i couldnt change it myself since its sealed

[Vern Houseman]

ya  it dose go away when motor warms up but dont let it go to long its not good for the head..... good luck.    Vern#20

alright thanks and since it's sealed i gotta send it to 600 right?

[Vern Houseman]

check your compression first see if your readingsw are close to 165 or if one is alot lower then the rest ?

[Schmitt20]

The compression on the first cylinder is about 120 the second is 120 the 3rd is 60 the 4th is 80. Is that a blown head gasket?

[Vern Houseman]

they should be up around 160 165 ,and all should be pritty close plus minus 10 to 15 pounds at the most, dose look like you have a prob ?

Brandon,
Did you test it hot or cold?
Do you have the ability to do a cylinder leak down test?
When was the last vlave adjustment?
Manual or hydraulic cam chain tensioner? You could get numbers like that if your cam timing jumps a tooth.

The best I have seen a sealed pump has been about 155 cold.  The main thing is that all the holes are very close.  I know guys that have fast motors that pump 130 to 140, but thats across ALL the cyl.  So 2 of yours are 120 that the other 2 are 1/2 that then I would say the head gasket is blown between, near, around those low cyl.

I did it cold and i will probably just take it to M and R motorsports in Beaver Dam to get looked at. Engines arent my department.

[Schmitt20]

would it squeak really loud though if it was valves? they havent been checked since last spring

[Schmitt20]

problem has been solved it was a blown head gasket. I had to send it to US Legends so i had a complete rebuild on it right away. Costed $2,200.
