"It can leak" really makes me follow all of my vacuum lines etc :) The other inspection i do are all the grounding locations. The ground cable between the engine and the body was turning green and got replaced with a marine / sealed lugs cable.

I love tracing all those ground wires those are fun.

I got that too, I’ve just left it on. Asked a mechanic and he said the bulb for the engine light might just be wearing out or dead. It’s not big issues u just can’t see ur engine light pop up if something was wrong, but if u have a scanner it’ll still scan and show u

It could be a bad ground somewhere or a combination of problems. The brake light junction box can cause you a lot of problems too.

What are the symptoms of leaking intake manifold gasket ?

@MattsShop 4 ай бұрын

Poor idle, misfires, bad power, alot of different codes, bad mpg, main one is a loud hissing noise

@M4sterT3ch 4 ай бұрын

You'll get p0171 - Bank 1 Too Lean and p0174 - Bank 2 Too Lean. Look at scan data, and long-term fuel trim will be very high, +20 or more. And if you rev it up to 2000 RPM and trims will drop down to near zero. Let off, and they go back up. That is tail tail intake leak sign.

@BruSitdee-kg2bu 4 ай бұрын

Here’s a really simple way wait to the car has warmed up and then rev the gas if it shoots water it needs intake gasket replacement. You’re welcome. Only aluminum engines are supposed to leak on start up. That’s why you have to wait till it warms up and if you were a white guy he should be no problem every time I turn around I just see white guys revving their cars. Every KZfaq video no matter how cool the car is he’s revving the fucking engine.😂😂😂🤣🤣🤣🤣😭

@@M4sterT3ch let's say i had all those signs is their any alternative things I should check before I decide to replace those gaskets like word for word every thing you said is what happened when I test it

@M4sterT3ch 3 ай бұрын

@JB-qr5io Yeah, the intake manifold gaskets and any vacuum lines going to the intake. It is not as common of an issue, but fuel injector o-rings can leak as well. Pull the fuel pressure regulator line off to make sure then regulator diaphragm isn't ruptured. This issue would cause a different type of symptom, though.

@@Daboy115maybe it’s not getting enough spark could be a faulty ignition coil/ distributor depending on your year or maybe it’s not getting enough fuel, could be fuel injectors or fuel pump. Check your battery connections as well. Make sure they are tight and not loose.I had a similar problem and it turned out to be a bad battery and not a very good connection if I recall.

Check your fuel pump relay, or 20 yellow fuse.

Can try a crank relearn with a scan tool if you don't actually feel the misfire. Engine running lean or rich?

Is the evap solenoid supost to wiggle a lot? That 10mm bolt is tight but the thing moves like crazy. My truck is a 01 2500hd 6.0 and I have a miss at idle in I think cylender 3. No codes but it threw one at 5000 rpm and it went away.

Yes it wiggles a lot it seals with a rubber seal that goes around the mounting bolt.
