Hey I was wondering if anyone would know if I can swap a I4 from a 1991 (auto) engine into a 1993 with the V6 (manual trans). They are both 4Runners Does this make sense?
My 93 got burried in the mud and ever since the oil pressure is wacked and I did a oil change looked like there was water in it did a flush but still have very low pressure.

I took a look in the air filter and I saw mud...I am now sure what is wrong.

Any suggestions would be great!
