    Question 18r - 18rc front rear sump swap?

    hey there, hopefully someone can help me out,

    I got an '81 hilux w an 18rc in it for free off my mate who blew the timing cover open. Now i happen to have perfectly fine 18r from rt104 corona at home.
    What I want to do is get either the 18r out of rt104 and into the hilux or, at very least, scab the timing bits off 18r and slap onto 18rc.

    eyeballing, it there doesn't seems to be any reason why they wouldn't swap straight over
    except for one issue.

    18r = front sump 18rc = rear sump

    As I don't really want to go into all the timing chain blah I was thinking of jus taking sump/oil pump off 18rc and swapping with sump/pump off 18r

    in my book for the rt104 the oil pump doesn't seem to have mating marks/notches and looks as though it should jus turn around in situ. also numbers of bolts match etc

    so whaddaya reckon, will my sump plan work or no?

    Swap pump / pickup around and the sumps will swap over.

    hey mate,

    as long as you chage the oil pickup and the sump, everything will be fine. No need to change oil pump!

    should be a piece of cake to do

    thanks guys, appreciate the help it will be happening this week (once I get engine hoist one mon, anyone in canberra got one i could borrow? I could use 2!! )so ill let u know how it goes.

    I'm gonna start a new thread about using the disc front end from my rt104 in a rn20 that I've recently acquired. I'll need a fair bit of advice for that too but I'm yet to measure it all up and get things clear so thanks again
