Question about 1994 Buick Regal Gran Sport

Car sounds like a Harley

Just purchased a 94 Regal, when it's running it sounds like a harley. I'm thinking it might be the manifold gasket, but not really a car repair person.

GM never uses exhaust manifold gaskets, it is a machined fit. The rear main may be two piece in this year, it depends on what engine the car has, you never say, if so you must remove the oil pan. Also if it is a one piece you need the installation tool to install the seal, if you don't do it right it will likely leak even worse.

94 caprice v8 an i cant spin wheels (burnout) what to do

Sounds like the timing is retarded. Loosen the distributor hold down bolt and turn the distributor counter clockwise about a half inch or so. Then drive the car. If it runs better then get a timing light and set the timing to 10 to 15 degrees before top dead center (btdc) at idle with EST disabled (if equipped) or if it has a vacuum advance with vacuum hose disconnected. Good luck.

My intake gasket is leaking how do i replace it? 94 toyota camry

It would probably be very beneficial for you to purchase a Haynes Repair Manual that will walk you through step by step for just about every repair mechanical and otherwise that you would need to undertake now and in the future. Toyota makes a very durable machine but eventually things wear down. I know the manuals can be purchased at most of your auto part store chains such as Auto Zone, Discount Auto Parts, Pep Boys or something similar. Tou will find a range of years included in several books for your specific year, make and model.Cost is around $20.00 They have torque specs and all other specs you will need. Another manual that is good but I don't see much of anymore is Chiltons. You can also look at a book store if that is closer to where you live but I'm not sure. Also could look on ebay possibly.
Just to mention this. I don't think that your oil would be leaking from the intake manifold gasket. The intake manifold distributes the air/fuel mixture from a throttle body which is like a carb only it uses a single fuel injector to control the fuel. Or, it would be a plenum that only handles the air distribution to the cylinders, with an injector for the fuel delivery located by each cylinder. Fuel and air or air under a vacuum environment An intake manifold leak is usually accompanied by erratic engine idle speeds that constantly change or are too high or too low. I would check the valve cover gasket, a clogged pcv valve, or another small component fastened in the area of the leak. Oil leaks can sometimes be difficult to track.
Hope this helps,

'94 VW Golf 1.8 petrol - engine cuts out and wont re-start

It could be. The car seems to be flooding its self as though you are driving on the choke all the time. Replace the air filter if dirty and clean all the breather pipes. Also check the accelerator cable is not snagged and is adjusted correctly.

94 buick regal grande sport

You could possibly have a blown head gasket. Is there an awful amount of white smoke coming out of the tailpipe? If so, that's likely to be your problem.
