smoking engine and leaky oil pan

i put a b16a1 into my 91 civic si about a year ago and i am having a little problem with burning oil. it ususally is the worst when down shifting and when i engage first from a stop. can any one tell me what i should repalce or fix. i also have a tucan industriesn cat so i know that amounts for some of the smoke but not the amout that i should be getting. also, i have a leaky oil pan. i put like 3 gaskets( not at the same time) on the old pan and i just got a new pan but i used a few month gasket on it and there is still a leake thats comming from the pan and its not the drain plug. can any one help me??

Ok for the oil burning do a compression and leakdown test to pinpoint if the leak is coming from the piston rings or the valve seals. What color is the smoke by the way? As for the oil pan. Make sure that when you put a new gasket on to clean both surfaces ver well and make sure no foreign objects are on either surface. When installing the new gasket use some high temp sealant around the entire gasket. I had a leaky pan and performed the steps above and haven't had a problem since. Also make sure you tighten the pan up according to the pattern listed in your service manual.:)

i dont want to sound stupid or bother some cuz i do know a fair amount about cars, but what and where would i do a compression test or a leak down test. the smoke seems to be a whitish color. what manuel should i use, the one for my car or one for my engine (b16).

thanks

You can rent or buy both the compression test kit and the leakdown test kit at a local auto parts place. They are really not hard to do and will give you an idea of what kind of condition the engine is in. You can just use the manual from your stock motor. The oil pans are very similar and the install procedure is the same.

This is a good how-to for the compression test.;)
