Reoccuring HG Failures

[jeffro22]

How many of you have had reoccuring HG failures and if so what did you learn find out from doing it again. trying to figure out what caused the failure and how to prevent it from happening again.

I had mine studded last year and already am leaking pretty bad. losing about 1.5 gallons every 200 miles. I am actually alot worse now then when I first took the truck to get studded.

I used the Black Gaskets, ARP Head Studs, deleted EGR, had heads checked and decked for flatnesss, Replaced oil cooler, and only got about 15k miles. and i was pretty easy on the truck!! What a PITA

I am leaning towards going with stock HG as I think the black ones are possibly an issue?

thoughts or suggestions are appreciated as I need to get a game plan together and make sure this doesnt happen again

how many pounds of boost are you running and did you notice any overboost concerns when they first went out?

what about your tune?

[jeffro22]

running either stock or DJ's/Vivians tunes. I was getting a slight overboost problem when I first got truck back last year. not sure why bc i was running the same tune. i did have the turbo cleaned/serviced when the truck was apart for gaskets. Even now on stock tune I see close to 30# according to stock boost gauge (not sure how accurate it is though)

you need an aftermarket (autometer) boost guage to get real numbers, even the edge has been off, there was a thread about this a while back

Do you have a monitoring solution to monitor ECT and EOT?

no, I dont think so. All i have is an SCT

You need to be monitoring ECT and EOT.. Just because you had a new oil cooler installed doesnt mean it hasn't clogged again.

I would look into a scangauge II or an Edge Insight CTS/CS. I bet the reason you head gaskets failed again was due to your oil cooler being clogged again. Need to be watching minimum while towing your ECT, EOT and EGT. Just my 2 cents.

The machine shop could very well have screwed you over, its VERY hard to find a decent shop these days. I have had a lot of engine work done by various machine shops and they ALL have their own opinion of what is right and what is wrong. Your heads can still be warped, your deck can be warped, and I have also heard that the Black HG's are 7-8/10 good, meaning 7-8/10 work out.

i have hard of other having the same failures with the black gaskets. I am pissed that I tried them since I ended up buying an OEM set at the last minute. Not saying thats the problem, but I shouldnt have risked it and just gone oem.

also, i hear what your saying on the machine shop. I need to check into that too. guessing i will need new heads at this point since they have already been decked once and are problably warped again

I had a cousin that kept breaking his snowmobile and the company asked him to became a tester for the company, because he was doing things with his machine that they could not understand, and the their testing was not enough to discover the machines weakness.
SCT needs you to explain how you do the damage to your truck, I feel its in the programing to breaking point that is your problem.
