Need to check distributor and timing. Oil sender is also near distributor, maybe it was damaged when intake was replaced.

'94 Gmc Sonoma 4.3L Starts loosing Power and making weird Rattle Noise when reaching operating temperature. Also water tank looks like there is a bit oil in it. Could it be the cylinder head gasket?


Oil in the coolant is usually an intake manifold gasket problem on these engines. If a head gasket failure the engine will normally overheat and give erratic temp guage readings. Make sure the oil level is full. Is the rattle noise coming from the engine? Some times the exhaust (converter) will fail and the catylist will seperate causing a rattle noise from the exhaust and plug it up giving a no power situation

My 2008 Chevy uplander engine light on and the code shows for cam shaft sensor and intake manifold what I do


The intake code means its leaking from the intake,bad gaskets, or a vacuum leak. check for bad gaskets on intake manifold. You can tell by putting a bit of oil around the maifold. if it is leaking the engine will flair up. To check this, External leak-- Coolant seeps through the broken intake manifold gasket to the outside of the engine. If its bad enough you will see coolant dripping from gasket. Coolant seeps through the damaged gasket to the inside of the engine, mixing with motor oil. If you suspect an internal leak, check your oil dipstick. Or if you have a substance under oil filler cap that looks like a milkshake, Oil is mixing with coolant. this means intake gaskets are bad, Now for the camshaft sensor, If you have a manifold leak. this could be giving you a false camshaft reading! Because, If sensor is bad vehicle will not start unless theres a wire problem. Symtoms of a bad sensor are--- engine sputtering, poor acceleration, stalling/inability to start. HopeI helped you out! Good-Day!

Hi, You could have a vacuum leak. Check all hoses that are connected on or near the intake manifold and throttle body. Good luck.

No oil pressure


If you have run it out of oil, then it's the bearings. These will knock at first start up in the morning. Replace the oil sending unit first. these do go bad and give false readings.

Dash cluster (speed and tach) do not reset and give false reading. Start and tach could say 4000 rpm's and speed at 80 mph in park.


Hello: You have a bad cluster. The only way to repair is to replace the cluster. It will also have to be programmed after replacement. The cluster was a high failure rate item from 2003 t0 2005.
