"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.
@@MattsShop do you do how to videos on some of the stuff that's a little difficult and there might be tricks to? I'm sure you got some tricks up your sleeve for repairs... Let's see em. Lol
Might sound silly bc i know you gave all the information in the description, but i have a 2003 chevy Z71, engines a V8 5.3 Z... is that one of the cars you're showing here? I have a intake valve that gets stuck open and need to figure out how to get in there and fix it 😅
My 2000 Suburban development a knock out of nowhere one day. I’m thinking my intake manifold gaskets were bad and water got into the engine causing a hydrolock on one of the cylinders bending a connection rod. Sucks. Ending up getting a used engine put into it
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
I have a 01 gmc Yukon Denali xl 6.0L I have a p0300 multiple misfires code I changed the spark plugs ( dealership) spark plug wires ( dealership) the coil packs ( dealership) & still have a misfire & my check engine light is still on
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.
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 RU-vid 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
@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.
what’s up man i got a transmission problem, when i drive my truck for a while it won’t shift from 2nd to third unless i let go a little of the gas pedal. Any ideas what it would be? Transmission was just rebuilt also and filter and oil have been recently changed.
I have an 02 silverado v6 4.3L that random misfires under heavy load. Usually, going up a hill. The code clears as soon i get on level ground. Im pretty sure it is a vacuum that occurs under heavy load. Any idea what it can be? Im thinking of those intake seals you kept mentioning
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.
Hey man im having issue with my 01 Silverado 5.3 not starting the truck starts on first try and it runs perfectly but when you turn it off and try the 2nd to start it just cranks no start only starts when you leave the truck alone sitting for hours I check fuel I check everything idk where else to look need some info where i can find the problem thanks
@@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.
I have an 02 s10 and I’m hearing a bad hissing sound I’m noticing it for a bit after I shut it off but I’m sure it’s probably also happening while running. It’s probably one of these leaking huh ?
