I have a bad oil leak, which I believe is going to be the rear main seal.
However, my vtec solenoid is leaking and I have two spots it leaks. In the middle and under the tranny. What should I change when changing the rear main seal? I keep getting told there is another gasket next to the crankshaft seal.

THE CAR IS A 99 CIVIC SI (EM1) 5 SPEED.
B16A siR 2nd gen

 

The front main seal??

 

no, not that one.
I'm thinking whoever told me to change another seal is full of it lol.

 

Start with changing your vtec solenoid screen/gasket. If you know you have a problem there its always best to start with the easy stuff. I have seen vtec solenoid gaskets leak all over the damn place. You may be surprised and have that be your only problem. Also you should have 1 rear and 1 front main seal. Thats it.

 

if you do a rear main you might as well change your clutch

 

YES!

Change the easy seals first, if the leak continues replace the main.
