i replaced my head gasket 9 months ago and put arp head studs in when i did it. i oil out between the head and the block right in front above the fan pedastel. i think itscoming out the back too but cant see. what would cause this? the most booost it ever sees is 45psi. i was hoping the head studs would hold longer than that.

 

i have a buddy with a 95, we replaced the head gasket 3 times,less than a year, once after ARPs installed.finally had to have the head milled flat & o ringed.more than a year no problems,money well spent.may be your next(best)step,no more issues or head aches.

 

how much did it cost for the head work?

 

Head may not be flat. Did it blow in the same place?

Block not clean/ not flat in said location.

Improperly torqued.

Bad gasket.

In that order.

 

You always have to mill head when doing HG replacement, it's pretty much a requirement if you want it to seal real well

 

0-ringing the head will usually be around $375, plus the cost of milling it flat in the first place.

Usually, with a full machining package and a good valve job the tab will be around $2,300-$2,500. It is money well spent.

 

redneck, I had the head off on my truck this spring because of a coolant leak on the right side near the front.
The shop sent the head to Northside Engine Rebuilders in Saskatoon.
The head needed to be squared. They did a completed rebuild of the head for $2600 before tax. We priced out reman heads from Cummins and other reputable shops and they were right inline.
I didn't really want to see this bill but with the 480,000 km and many hours of idle time I should not complain.

got .006 milled off the head. puttin er back together tonight.

 

when and how many times should you re torque these arp studs?
