Engine compatibility

[AKFJ]

I'm running an 86 fj 60 with a wicked amount of blow by. Cylinders 3 and 5 show 20 psi of compression dry and 50/60 psi with a wet test. Ultimately I want to rebuild the motor but this is my DD so i want to limit down time. There is a complete 2F motor, carb to pan from a '77 fj40 for sale that i was considering swapping in to buy me some time till the spring at which time I will have the time to rebuild my existing motor. Can anyone fill me in on any unforeseen issues that need to be considered before I contact the seller?

Thanks in advance

The '77 block is not drilled for the mounting of the power steering pump. You would be better off locating an engine from a FJ60 or 1980s FJ40.

a head gasket can be swapped in a weekend, as long as there isn't a disaster lurking inside...second vote for don't bother with the 77 for the same reason that there are no power steering mounting holes in that block. The 77 might be a suitable candidate for a 2fe if one swapped in flattops and was going to use the motor in a 62....But not a 60...

Thanks guys. I'm pretty sure the compression issue is not related to the head gasket. I have smoke and air flow emanating from the oil dip stick tube, and from the pcv.I'll move forward on my engine rebuild in the spring.

Blowby like in the following pic (that heater hose is connected to the valve cover INTAKE from the air cleaner)???

In this picture, it has become an OUT vent for the motor

That motor is now out of the vehicle and is now history.

I learned about blowby the hard way as well.

Yeah, I'm having identical symptoms and the smoke is coming from the vent tube that feeds into the back of the air cleaner.

A 60 series or a 80 series is the best way to go.

Ill put my ear back to the ground closer to the spring.

Can't speak for the 77 working, however as for the power steering holes not being in the block, I wouldn't let that be the show stopper. You should be able to use a Saginaw pump with either an aftermarket bracket or one of your design. I think it's a better power steering unit anyhow, and way cheaper if you ever need a PS pump replacement. JMHO.

Thanks cruzer man. I haven't considered swapping out the power steering box for the Saginaw.

You might consider swapping out the whole motor for something else, unless you really want an original.

I looked at the costs of rebuilding my 2F, and they just went higher over time, and not much return on torque.

That is why I went with the SBC, but of course there came with that consequences, etc.

My FJ60 is no longer my DD (85 miles round trip costs too much), but I want this FJ60 to last and be able to do the stuff outdoors I want, so I am spending the money needed to do it right according to my wants and needs.

If you just want to get it back running again as is, then yeah, find a FJ60 motor you can rebuild and do it right. Would love to watch your rebuild thread

I'm staying optimistic and hoping to get it back up to snuff with a re-ring. I'll know more when I tear into either mid winter( if I can find a warm place indoors to work on it) or in the spring. I did manage to to locate all the parts to complete the 2FE conversion, so I may jump on that parts lot and put them away for the rebuild. Still working out what direction to go with it.

ah, but doing the rings also means the head is off and it is a good thing to redo that head. when I did mine is made a great difference. That head is now in Colorado going on a 2F. But that head cost me $500 or so as I put in stainless steel valves and other upgrades and the head gasket which costs $200 as a kit.

then maybe new RV CAM, which requires new lifters .... and so on.

I am saying just make explicit decisions with knowledge so you don't get caught deep in a rebuild and find something that goes more ouch.

hope it works

The fuel injection parts I'm looking at will include the 3FE head, I'll rebuild that in anticipation of the tear down. I'm not looking to push the motor to max power output, Just looking to gain a little, and maybe squeak out a few more mpg. Thanks for the advice, I'll keep reading up on the conversion.
