Cracked head?

[poweraidon]

This is a tell tale sign of a cracked head right?

What would be the cost to repair it?

And I have a wheeling trip with a few of my buds tomorrow can I still take my hummer?

I thought we all learned a lesson from one of the previous thread. "Don't go looking under your rig."

Can you go in MS paint and circle the area of interest because I don't really see anything that stands out.

eta: oh is it that darker area on the head what you're talking about?

I don't see the image but if you have a cracked head look for overheating and coolant in the oil.

Remember water will not compress and if you get water in a cylinder while running.........................pop goes the engine.
Probably break a piston or rod or even crack the block.

The side of it is kinda leaking

I'm losing coolant

I see the image now and cannot tell but looks like the valve cover gasket may have "weeped" a bit of oil.
Clean that off and see if it comes back.

Do a compression check and see if all the cylinders are about the same.

Check your radiator if your losing coolant. I don't see a cracked head. I see a dirty engine.

And it was a small weep at first but it expanded a lot

Do you think I should be ok taking it wheeling?

Doesn't look very serious to me, go have fun! You can clean the engine when you get back

I'm just scared cause I've been losing coolant and my engine always sits really close to 3/4 on temp gauge... But really is a cracked head really that serious what if I dont replace it?

I was just commenting on the photo. Do you think you may have just blown a head gasket? That is more serious. I would get it fixed right away.

Anything like a cracked head or block I would get fixed right away too.

Is it blowing white smoke? Coolant in the oil?

Idk I'll take it to a shop and find out what's wrong with after the trip but I don't have white smoke or oil in coolant

No codes?

No codes?

I had a misfire on cylinder 2 but I replaced the coil pack and I'm pretty sure it went away. I'm still not certain cause my cel is always on cause I have a evap leak somewhere. I'll take it to autozone and have them check codes for me.

Lol. Clean it off. Start with a pressure test to your cooling system and check your spark plugs. Compression test would be good. But a new gasket at the cover might be needed.

If you're losing coolant, and have no spots on your driveway...then check the engine dipstick. If it looks like cappaccino instead of 5w-30....you got a problem.

BTW...that's about ten times cleaner than my motor.

My vote is radiator. OP how many miles are on your rig?

 

[poweraidon]

The oil looks fine and I just changed my radiator a few months ago... I got the radioator off of ebay for like a hundred bucks so it's not very good

Silla radiator? I've had extremely good luck with mine. Just make sure the radiator neck line going to the overflow jug isn't seeping. The pic I saw just looks like a valve cover gasket.
