i've got a pretty bad oil leak on my 84 22R,i believe it's coming from the timing cover,but not really sure...i took pictures awhile back and haven't seen my camera since...think it got left under the hood and is long gone...

i looked through the chilton book for timing gasket replacement and it looks like quite a project....do i really have to remove the head? what a PITA...any shortcuts for this? helpful tips?i really didn't wanna get into that much,but i gotta do what i gotta do...i don't plan on replacing the timing chain,just want to keep oil in the engine....anybody got any suggestions on making this easier?

 

I would take a closer look at the front crankshaft seal, those are a more common source of major leakage than the timing cover unexpectedly springing a leak.

 

this! both my 77 and my 83 leaked from here, IF you do pull the cover DO NOT forget the bolt under the cam sprocket. Havent done mine yet but have been told and read a bit if you are careful you can do it without pulling the head.

 

thanks...i'll look at the crankshaft seal today...oil is everywhere so it's hard to tell where it's coming from...i also made the mistake of using some synthetic oil cause that's what i had on hand...i wasn't aware it would make it leak worse...

 

I took it off the road about a month ago...now that it's dried up a bit,i can see Nook hit it on the head...crankshaft seal...really clean around that area...



Always the one to take shortcuts,i'm wondering if it's possible to change the seal without pulling the oil pump...Chilton says to pull the pump,then swap the seal,but i don't wanna...my grille is missing,and i've already pulled the radiator....looks like plenty of room...any other reason to pull the pump?,other than to sell gaskets...

 

I believe the seal you need comes with the seal for the oil pump and a sleave. Might as well do it all sing you have to take the pulley off anyways. Been awhile but I think its only 4 bolts to take the pump off.

 

Good point..didn't look all that hard to pull it off...i gotta lotta grime to clean up to be able to work on it,and no degreaser til i go to town...i'll get the other seal and gasket...gonna need an alternator,too,but not in this week'e budget...

 

You don't need to pull the oil pump to replace the seal unless you just want to, pull the crank pulley, and pop the seal out and replace with a new seal, clean the pulley seal surface with some emory cloth , or if the crank pulley is worn badly, groove worn in it, you can either use a speed sleeve to repair the seal surface on the pulley, or they make a couple different width seals, the thinner width seal can be driven in a little further so it rides on a fresh spot on the pulley so the sleeve isn't used. easy fix.

 

Sounds like fun...gotta go to napa tomorrow,prolly hafta order the seals...that'll give me a day to degrease a bit...

i got an offer on the F-150 i bought to replace it,making me a quick couple hundred,and the yota's only got 78K on it...almost...



I bought this a year ago with 52,000 miles for $200,put a starter in it,and hammered out some dents when the kid rolled it...it owes me nothing



It's on CL for $400, and no bites,so ima keep it and go from there...i aim to show you guys how to cob...been out of work 4 months,and i'm so broke,i can't even pay attention...and yeah, i know it's ugly,but i kinda adore that...does that mean there's something wrong with me? Or is it just a yota thing?...

Thanks for the input

 

Chances are that crank bolt will be "oh my gawd WTF" tight. Make life easy and pull the coil wire, put a breaker bar under the passenger frame rail with the socket on the crank bolt and hit the key. Voila it just came loose. The last one I did the bastid was so tight I hit the key and the truck just leaned to the driver side so I let off and hit the key a few times quick and it popped free.

 

I never would have thought of that...i was thinking yesterday i would try cleaning the pulleys real good,put the fan and belt back on and try to break it loose....you just saved me that trouble

 

Main seal

From the looks of your pics its probably your main seal. If you buy a timing cover gasket set at napa it comes with everything you need. You dont need to remove your head or your oil pump. But if you want to make it cherry you should drop your oil pan and replace timming gaskets and the replace oil pan with a new gasket or else you risk loosing oil where your timming cover meets your old oil pan gasket on the bottom. BTW becarefull not to tighten down that bolt under you cam sprocket too tight. It doesnt take much to crack through the bottom.Good luck

 

Main bolt

You can also put a strong screwdriver thru your cam sprocket to take off your main pulley bolt.

 

WhiteTrash, that trick worked great,popped that bolt like nothing...learn somethin new every day...decided to do just the crankshaft seal,and hope that does it... no doubt it was leaking....

and i see why they recommend pulling the oil pump- the crankshaft is in the way of prying the seal out,but with a little finesse,it came out...did a good bit of cleaning up with rags,a screwdriver,and a can of EngineBrite...still pretty greasy,but i'll deal with that later...

Before: After:

well,during...but still more to do
