G,day all, have searched all through this site but have not found anyone with this problem. I have a 1uzfe in a 37 Chev which has been running fine for the last 12 months and done approx 8000km's since it went in. I was taking it to have the trans flushed and got about 35 km's from home when it gave a bit of a shudder and wouldn't pull then i smelt burnt rubber so i pulled over straight away. Opened the bonnet and could see smoke coming from under the covers so i thought seized idler or water pump. Both were replaced before fitting the engine to the car but stranger things have happened. Got it home on a trailer and started pulling things apart but no joy with the front. Motor was solid. Pulled tappet cover of and found front cam bearing seized on both sides and second bearing just starting to nip. I didn't notice if i had oil pressure when it happened but has always been very goodand had just done an oil and filter change prior to this happening. Used Gulf western 15/40 and had normal oil pressure after service. I know that i have to tear the engine down to check everything but have just posted this to see if anybody else has ever heard of this problem before. If not i will reveal what i find when i get it stripped.
