Head gasket leak

Doat91 · 05-03-2012, 07:52 PM

So it seems I have a small head gasket leak and I am debating on whether or not I should torque it down until I can get it changed with ARP studs. What are the pros and cons of torquing it down at this stage vs not torquing it down?

I know this has been beaten to death but I haven't be able to find a thread with an issue like mine. Thanks in advance.

tourqing it down will ensure you car lives untill you can get the studs and new HG. if there is any leaks torquing them might hide and prevent damadge ( remind you this is only a band aid not a solution) i would buy a good quality meatal head gasket whith the arp studs and torqu them down to proper setting useing the proper lubs for this application and use the proper sequence to take the head off and on . also clean the deck and heads while also making shure the head has not become warped,

this is all covered in the mk3 FAQ'S there would be a good place to look for further help

I am debating on going for a metal gasket since I don't plan on going for high power, maybe 400hp tops, also there is the cost issue with the gasket itself and machining the head and block, etc. I planned on getting an OEM gasket and my shop will machine the head anyway to ensure a good contact. Yea I will replace the head gasket I just don't want the coolant to keep getting into the motor or getting pushed into the overflow tank. I plan on doing it tomorrow in the proper sequence, torque it down to 72ft/lb right?

I thought that 72 was the original specification, I believe people do them an extra 20ftlbs no?

let me check the FAQ's and ill get back to ya

i checked the FAQ's and it says 72 i havent been on the fourm THAT long to have heard about going 20ftlbs over, i think useing the proper moly lube the 72 should be just fine( the arp studs should tell you what lube to use and what torue settings, only if there specific to your car tho) heres a link of the FAQ'S which explanes just about everything

P.S in my opinion if you got the heads out and putting a new head gasket might as well go whith MHg just because your there and that little extra will give you peace of mind down the road and if you want to go a bit higher on the HP level you dont have to worry about it

The car comes with 52ftlbs stock that is how it came from the factory and that is the reason why 7m motors have this issue lol. I hear people torque them to 72ftlbs from 52ftlbs. I'll think about going with a MHG just right now I want to temporarily fix this small leak so I am not so nervous when I have no choice but to take the car out somewhere.
