As long as that's not rust around it it should be OK. If it is rust then yes treat it.

There is 1 ground on the lft rear of the head that seems to be a weak spot.

The "wooly worm" can be repaired with duct tape of replaced with HVAC/dryer vent (the metallic kind) tubing, or pay the General $50 or so. Search "wooly worm" been talked about a lot.

 

I'll check that ground too, thanks for the input and I fixed it by cutting it and siliconing the tube back to the elbow, i might reinforce it with duct tape there too since its still not back together.

 

When I had my engine replaced the mechanic boogered up my wooly worm a lot. I took some Elmer's glue and some time and put it back together.

That was around 50,000 miles ago and it is still in good shape.

 

FWIW; the best way is to pop the other end out of the body hole leave the filter end connected. Then you won't be complaining about that upside down hose clamp.

 

hey donbrew, i cant seem to find the ground that you mentioned left rear head?

THANK YOU!! my hand must have gone over that thing 100 times... its snug and clean. put the car back together cleaned the K&N as well. will see if the codes come up again.


Also,, i didnt include this as i didnt think much of it, but when we were reading the codes the P0013 and P0014 codes were listed more than once.

 

Back from O'reilly's and codes P0013, P0014 and P0107 are still present.

 

Have you checked the resistance of the VVT Solenoid? It should be 8-12 ohms. If out of spec it needs to be replaced.

Re the MAP sensor code p0107 - here is the procedure for replacing it - https://www.chevyhhr.net/forums/how-...acement-49757/

 

If the codes were present more than once it is important to know which types they are; current, stored or permanent.

If they are stored or permanent a battery disconnect will clear them. If the light comes right back on that means it is not a transient problem.

If you have to replace the parts at least they are shade tree jobs, figure about $210 in parts. It is odd that a VVT valve and the MAP sensor would break all at the same time.

And here is how to test the MAP sensor. https://www.obd-codes.com/p0107
