I need to locate the camshaft sensor on a 3800 series ii V6


Here is a link with a diagram about half way down the page that points out the sensor as number 8. It looks like it should be near the oil filter just up and over a bit. There is some good info on this page to that may help. Good luck! Have a great day!

We have a 95 buick riviera with the supercharge 3800 v6 engine. It overheated, usually runs at 200 degrees and blew the oil dipstick up and oil splattered on the engine. Oil level is ok and oil...


The overheating might be caused by a thermostat stuck closed, have it replaced. That should fix the overheating, as for the hesitating, run a scan on the ECM module to make sure you dont have any codes, clear if any and fix anything that might've gotten damaged from the overheating.

1995 buick lesabre limited, oil gauge issue


Could be two things, your oil pump pick tube is clog, oil pan would have to be drop to check, or your camshaft bearing worn causing low oil pressure,I would not say piston rod bearing or main bearing, cause there's no knock noise. You will have better oil pressure when cold due to oil much thicker. so I would forget about a bad oil pump.

My 1999 grand prix 3800 v-6 stalls when stopped and hesitates around 2000 rpm


tough one, has many things that could be wrong..to give you some idea...Air filter, a loose air hose, gas filter,oxygen sensors, sparkplugs wires or even crossed wires will all play a role in the hesitation that your car is producing, I have 2 grand prix and one of them is hesitating on me right now, I know its the oxygen sensor but I cant fix it now, dont have the money to. I know it wastes more gas but oh well for now! Try testing first.

Buick review


Good engine 28 mpg+ hwy. These 3800 engines had upper intake problems and would leak coolant into the combustion chamber. The new ones were re-designed and do not give any trouble. My 90 buick 3800 has 295000 miles on it. If yours is supercharged it does not have that intake problem.

I HAVE A 93 BUICK SKYLARK CUSTOM
AND I HAD THE SAME HESITATION.
I CHAGED GAS FILTER, AIR FILTER, AND USE SEA FOME IN MY GAS TANK AND USE IT ALSO TO CLEAN THE INTAKE SYSTOM, AND IT HELPED ALOT. TWO MONTHS DOWN THE LINE HADE THE SAME HESITATION AND IT WAS ONE OF THE INISION COIAL PACK WAS NOT GIVING THE ELETRICAL SPARK TO THE PLUG.

Buick sounds like a dying chicken


Do you have the 3800 V6? It sounds like a bad bearing. Most likely the tensioner pulley or alternator.

Im assuming this is the Series I 3800? If so, if you can email me I can send you some directions on the process. Its for a Series II 3800 but it should be similar. If you cant email me, post up and I'll see what I can do.
