Noticed last spring my coolant was down a little when I did my oil change(every
3000 miles). The first time I just topped up the over flow a bit and next oil change it seemed ok again, there was never any sign in the oil etc. This past fall I noticed the coolant was low in the over flow again and coolant leak stain under the throttle body on top of the block, so I figured the intake!Again I left it be for when I had more time as it leaked very little and I figured no big deal it's on the outside. I finnally got a around to changing it here this week and did a little searching on the net!
Boy I wish I had searched the net a year ago and replaced it then!! It looks like I was getting a bit in the oil as there was more slude then I would have liked to see on top of the vavle covers. The cam surfaces looked good though.
It's a fairly big job as its a pain to get at things but not too bad. I replaced the gasket with an updated one and new bolts etc. I asked the parts guys at GM if it was a common problem. They said "not really we do the odd one". But yet they had 15 gaskets in stock!!!
So question I have today is does anyone know if this new style gasket has solved the problem? It is made a bit different and they tell you to use new bolts and a different torque spec.
Also whats the deal with dexcool I've seen mentioned on here?? Is it bascially you have to change like the old green stuff every 2 years and not leave it in there so long?
Thanks
