Coolant leak in a 99 votec Yukon???

[yukonjon]

Just ordered the parts for everything. Haven't done it yet as I'm out of country for the next few weeks. Should be ready for me as soon as I get home. It def wasn't the heater connect leaking but I'll replace it anyway. You guys just been buying those at autozone or is that a dealer part?

Ive decided im going to go ahead and do the spider injection, intake and head gaskets, valve adjustment, and clean and powder-coat anything I can while its apart. Not in a hurry to get it back up so I'll take my time and make sure everythings the way I want. I've also got a brand new set of borla shorty headers I might throw in. I know they don't do much for performance gains but I've got them with no plans for them unless someone wanted to buy them.

Whats the difference in quality between the dorman gasket set and the felpro. I heard the felpro wasn't as good in this case but can anyone confirm this?

Do not buy dorman gaskets. Buy only felpro. They also sell new lower intake bolts too. Want a little extra umph put comp cams 1.52 rockers in there. Only $200.

Whats the gain with the rockers? I was tossing the idea of a cam around but hadn't thought about rockers yet. Will def do the felpro gaskets then.

read the product features section. these will fit a OBS vortec with no modifications to heads needed. just install and adjust as if they were stock ones.

A similar product review said these chewed up his pushrods. Just wondering if you installed these and have not seen any issues.

well for a vortec obs those are the wrong ones which would mess up the push rods if he used it on such but he might have messed something up too. like improper install. you want 1417-16 like i stated. I have not put them on yet cause i have other issues to deal with at the moment but don't let that deter you. you need the self-aligning type.

I went through the "make sure this part fits your vehicle" at the top of that page. It says this item does NOT work with my vehicle.

This is the page, its at the top.

and it is because 1. there is the legality of emissions. and 2. trying to get application data before and after a crossover design is a pain. But you know what I will very some engine block design info and some other data again to verify again. will also talk to several at comp cams AGAIN.

and for what is is worth I will get some as soon as I can and put them on to be the guinea pig. I just don't know if it will be in june or july. so many other priorities right now.

so just went thru gm data again and the rockers arm assemblys are the same between obd1 and obd2 on obs vortec 350's. hence the 1417-16 which fit 95's for example which is in the application guide should fit all vortec 350 L31's.
