1986 toyota engine ID 22r or 22re

I am not only new to the forum but to Toyotas as well, I just bought my first 4x4 in 15 years. I did a compression check on my engine and my #2 cylinder is only holding 90psi but the other ones are between 130-140psi so I think I need a head, but I dont know how to tell a 22r from a 22re my truck is carburated. My next question is how hard is it to install an efi engine in place of my carbed engine

you have the 22r .. 22re is the fuel injected model

how hard is it? Pretty simple if you know your way around these motors, but you dont since you didnt know what motor you had hehe

you can do a conversion on that 22r to a 22re.. its not 'easy' but definetly not incredibly difficult. Just sourcing all the right parts and such

The only draw back to the 22r is inclines and high altitude but if you're not concerned about hill climbs, decents or travelling in the high mountains theres really no good reason to convert to a 22RE, they get the same gas mileage and the power difference IMO is unoticeable.

Look into just fixing the motor you have and possibly rebuilding the carb and you'll be set.

*I have two 22r's.

low compression alone doesn't mean you have a bad valve/head. Did you try doing a quick "leakdown" check by adding some oil into the spark plugs holes? I would. If the compression goes up then it's your rings if compression stays the same it's either a head gasket or valves. Since your other 3 are about the same (although low min. spec is 150psi), I would lean towards rings or valves. Either way, a new headgasket would be put on. A real leakdown check with pressurized air will tell you valves or headgasket.
