Possible head gasket leak?

[dorinights13]

I've been loosing coolant from the reservoir and I found one of
The coolant lines inside the intake mani leaking so I replaced it. Filled the radiator up with coolant burped it. But I noticed as I gave it gas air bubbles where popping up. Is this a sign of a hg leak or just air in the coolant lines coming out? It's a rebuilt sr20det with brand new oem gaskets.

If the cooling system has been properly bled, and there are still bubbles in the reservior, it is likely a HG leak.

Bleed it good, possibly with the front end jacked up high to get all the air out of the heater core, drive for a day, then check again for bubbles.

all i can say is dnt sych urself out like derass said jack it up or just shake car while its down and drive it for a day if u get mad white smoke or water dropplets coming from the tail pipe then u probably have bad hg

I'm no bubbles coming from the resivor and I never see smoke or water coming from the tailpipe. I guess I am just over reacting

If its not smoking or overheating...I'd just top that shit off. Put the cap back on, keep an eye on your overflow. If you see it bubbling when the car gets up to temp, thats probably combustion getting into the coolant system.

Only way good way 2 know if the hg is bad is do a leak down test

Although a leak-down test will tell; this is not entirely true- pinpointing a blown HG can be as simple as popping the hood and seeing oil pouring down the block ;)

I have NEVER had to sit and bleed my coolant- Even on a bone-dry, fresh rebuild. Right, wrong or indifferent- Servicing it up and topping it off as needed until it no longer requires coolant has worked for me every time. Disclaimer- My car is driven 'normal' more often than hard... If I were servicing it to go immediately out for hot-laps & such, THEN I would definitely take the time to bleed the system.

There are going to be air bubbles working their way out. Like Ray said- Until it starts smoking, drinking coolant, losing power, boiling out the overflow etc; just top it off & drive... After a few times of topping off, it will likely be fine.
