i replaced thr front oil seal in my 1986 toyota pickup 4 whl drive 2.4 engine manual trans after i replace the crankshaft pulley i put all the parts back on ie;radiator shroud ect i start the engine and about a minute later the oil blows out and the seal pops out, there seems to be a gap between the seal and pulley, the pulley shaft has wear ridges on it someone said to put a carnkshaft sleeve to stop the leaking and keep the seal in place?
look up LC Engineering on the web, they have what's called a seal saver, it's a sleeve that goes on the back of the harmonic balancer/crankshaft pulley, it has a real fine/shiny finish and it works really well.
Try using a factory seal (oem), the new seal is made thinner , so the lip of the seal is away from the groove. No doubt the new seal you are using is as thick as the old one.

They are right. The sleeve will seal against the crank seal. The ridges are what is letting the seal leak. I install sleeves quite often on older models, the success rate is pretty high.

I have no power to anything in my 1986 pickup, replaced broken ground wire, there is a white wire from the battery cable that appears to have broken off of something. Don't know where it goes.
