Seafoam is petroleum based cleaner specifically designed for the fuel system
we use seafoam at our shop because of the cleaning agents and its not to harsh on the internal parts of the fuel system, be careful with some of those other fuel cleaners out there they contain alcohol to help with moisture but the alcohol can have a bad effect on the emissions system IE 02 Sensors and charcoal canister, I've seen a newer car jump and engine studder using it, your best bet is to only pour the seafoam in the gas tank and you can also use it in the crank case, also another highly recommended product is Lucas it's called Tune Up In A Bottle that works well also.
Leave the intake cleaning up to your mechanic because some of the newer car have and electronic throttle and you could cause more damage than just burning gas.
No, it will leak.
usually your intake manifold is ok...the manifold gaskets are prone to failure..they are plastic with rubber impregnated seals...if the manifold is actually pitted, you can repair with JB WELD then sand smooth.... ase master certified tech
I wouldn't recommend it. That's kinda important to regulating your fuel/air mixture, which ensures as clean a burn as you can get, and also prevents detonation in your cylinders, which is really, really bad.
you need to make sure your plugs and wires are ok, if it is still rough 9 out of 10 chances it is your intake manifold gasket.
clean trottle valve air intake model
crankshaft-camshaft timing, clogged exhaust, plugged intake, intake manifold leak.
it's located under the intake manifold. the knock sensor is most likely ok' the porblem is the short wiring harness from sensor to main wire harness.
there wouldn't be any coolant in the oil if your intake manifold gasket is shot. so its the gasket. A cracked block or cylinder head would render the motor unstartable, so that's a lie from the mechanic. Find a different one you can trust.
No, the brake booster operates off of vacuum not electricity. If the booster isn't working then check the vacuum line going from the intake manifold to the booster. If the line is ok and not leaking then you need to replace the booster.
NO! You could run a compression test on an engine with NO intake manifold installed, so a leak of any size will not affect compression. The only things that usually affect compression is your rings, valves, and valve timing. if you have low compression on only one cyl, then valve timing is probably OK. With the piston at TDC removed the spark plug and introduce low pressure air (20psi) into the cylinder. If rings are bad, air will go into the crankcase (air comes out the oil cap), if air comes out the intake, you have an intake valve concern, if air goes out the tailpipe, you have a exhaust valve issue......Good Luck
As long as the woman is clean and STD free, it is OK.
seafoam you can buy it at any auto parts store it works really poor it in your tank and it does the rest
