How many have blown a head gasket?

[mattman347]

I was just curious to see who on here has blown a head gasket with hybrids? What size were the injectors? How many miles on the truck? Just looking for some statistics. Also post if you still have the stock bolts and you are running a 238/100 or higher.

Smokedout250 blew a hg before he sold his green '96 SCSB. Was running 238/100's I think and stock head bolts and s366 IIRC. I think 200 something thousand miles were on the truck

he had 160s with an 80 or 100 nozzle. No proof the head gasket was blown either.
Its all in the tuning, keep the boost under 40 and your golden.

300/200's and stock bolts for over 5k. 191k on the clock.

Todd blew a hg with arps, 238+ injectors and I might be adding another one to the list with h11s.

250/100s on stock head bolts for 20k miles. Have some h11s waiting to install one if these weekends. Hitting over 40 Psi if I try

Thanks for the posts guys! My father in law has hybrids in his bone stock 03 for the last 10,000 miles.

I blew both head gaskets with 200/100 with a stock turbo on my 97. Make sure you have good tuning. Truck has 250k on it.
