I have a 1995 lexus sc400, its have about 156k miles on it. There are a few leak that i found out from a mechanic. Here the list of the list.

Tansmission oil pan gasket leak
Engine oil pan gasket leak.

After changing out my spark plug myself i found oil on my spark plug.
Can someone please tell what is gonna to happen to my car if if this don't get fix soon?

Also which leak should i take care of?


I would like to do all the work myself, is there any mechanic or experienced member who can explain step by step to change the engine oil pan gasket?

 

THere is no oil pan gasket. The oil pan is sealed with Toyota FPIG...As far as the oil in the spark plugs, your valve cover gaskets are leaking. You could do this job by yourself however from what I have read, be ready for a lengthy job. I know the write up is out there, I just can't remember where. If you search, you will find a bunch of info on the SC300s but I think lextreme.com may have the writeup. If you don't get this fixed, your car isn't going to die tomorrow but as with any leak, the leak will get worse and worse.

 

then what is the mechanic is saying, he said the the engine oil pan gasket is leaking,
well anyway how much do you think it cost to fix that?

 

maybe he is talking about the upper oil pan..I don't know if that one has a gasket but I know the bottom one does not use a rubber gasket...it's a sealant. It could still be leaking and needing new sealant. If it is the upper pan...major money. The lower pan will cost you minimal. YOu should do the lower pan yourself

 

can you explain how to do the lower one, and please describe what is a sealant? and how much money are you talking about?

minimal money...you better hope its not the upper pan because that means engine hoist

 

thanks alot, hey by the way what kind of oil should i put in? thanks in advice, have you done this before, what kind of oil should i buy? i never change my own oil looking forward to.

 

You should fix all leaks. What part of California do you live in? That parking garage looks very familiar.

 

ima do it one by one, short of cash rite now, which one should i do first?
Lower Engine oil pan gasket?
Transmission oil pan gasket?

The picture was taken at the san francisco airport

 

Do the easy ones first...oil pan and tranny pan. Then worry about your valve cover gakets. Just use 5-W30 oil. That is what the car calls for. You could go expensive( about $6.50 or more a qt.) and get mobil 1 or royal purple(both full synthetic) or get the regular pennzoil etc. 5-W30

 

and how many carton will i need for my v8 engine?
thanks ahead you are a big help

 

5 qaurts.. each bottle is 1 quart

 

thanks man damn you a big help
