you wouldnt believe how many 3500/3900 gen 4 head gaskets i have done for oil leaks and oil consuption. New HD gaskets are black sealant, old style is blue. headstuds and black gaskets i wouldnt worry about much mars

Very good info man, Thanks for that. You're talking head gaskets right and not LIM ?

Mars, your threads are one of the reasons I visit here almost daily.

Yes he is talking about the head gaskets. At my work it is common to see two or three a week in the shop.

Cool, I didn't realise people read this stuff...

I guess now I feel kind of obligated to get better quality pics for the next update..

How much did that intercooler run you, mars?

Ebay for 147$ + 90 to ship. Just search "CXracing 31X12X4" should get like a million hits.

Mars, you're also my inspiration for a v6 super street car instead of being another guy with a bbc :P.

I am surprised about how many head gaskets you guys are doing though. I've seen very few on the 3.5/3.9 but a ton on the 3.6..

V6 3.9L head gaskets oil leak 170k

3.9L V6 170k miles with Right (back rear) head gasket leaking oil a bit... sucks.. All fluids clear and no overheating.
1) Whats typical labor hours needed to do that?
2) The front part of the engine is bone dry... Shall both head gaskets be done at the same time or one leaking side only?
3) What else would u recommend to replace/reseal/adjust along with it?
/// Should I leave it alone and drive until it gets worse..?
Thanks.

do both at the same time. labor time is 10 hours or so, actual time to do it with out power tools prob 6hours. using power tools and doing countless i can do impala or g6 in 3-4

Sorry about this horrible update, but I was in Jamaica on a holiday. back home now and still working on the car :

It's a throttle cable braket for my LS1 75mm TB. Works perfect and looks OK I suppose.



Fits perfect !




I am done all the intercooler pipes, but didn't get a pic of that. I really have to find my camera or purchase a new one.

I'll get better pics for the next update.

Mars,do you still have your cam actuator?

[Mars]

no garbage. Sorry. I threw out everything from that motor.

All good, got a little side project I'm working on for when I "upgrade" to a VVT engine, and I need some "mock up" parts...

OK, small update again.

I picked up a used 3.45 Borg warner rear end. Slightly lower then the 3.27 gear I have now, hopefully helps launch.



Going to be doing the following to it, I have all the parts, cept the spool :

-Full drag spool from Australia.
-TA performace rear girdle cover
-ARP carrier bearing studs
-Extended wheel studs
-Spohn LCARB's

Still 2000$ cheaper then a fabircated 9" rear. Should hold to my power level. (should)

I got the driver's side hotside mostly done, using a 3.9 manifold for cheap reliability and simplicity. Going to keep both banks seperate like the old setup for twinscroll. 38mm gates again, these are CHEAP EMUSA gates and they are awsome for the money. Highly recommend them. I can't see this being much much worse than a header. Hell LSX people make 1000HP on truck manifolds, so, this should be OK.

how much longer until we have a startup vid?
