patman Posted May 27, 2018 Share Posted May 27, 2018 I’m wondering if anyone could give me some advice please on these 4e-fte engines, my engine was built just under 20k miles ago and recently it has spun a bearing on the crank, and I’m trying to get my head around why, when it was built, everything was done right, pistons/rings, Toyota bearings used, everything was measured right and all tolerances were correct, I used the usual millers oil to run it in, then always used 5w 40 fully synth Mobil 1 oil, I’ve always had a slight oil leak oil pump crank side, (seems most do) so I’m trying to figure out why this has happened, if anyone has go some answers I would be most grateful, I’m thinking of just sorting out the bottom end, and leaving the pistons in, as they only done 20k aswell all opinions will be answered thanks Pat Quote Link to post Share on other sites

maddox710 Posted May 28, 2018 Share Posted May 28, 2018 Could just be bad look that maybe some junk has block an oil gallery. How was you driving at the time? Quote Link to post Share on other sites
daniel_g Posted May 28, 2018 Share Posted May 28, 2018 Low oil level / pressure, or incorrect oil clearance normally. The strainers on these clog with excess sealer. Also worth having the sump baffled if you do any track or quick driving. Quote Link to post Share on other sites
patman Posted May 28, 2018 Author Share Posted May 28, 2018 Thanks for the reply lads was driving (just before I pulled up outside my house and noticed it) about 80mph down the dual carriage way, not booting it all all, oil pressure (from the gauge) was still showing normal always the same, although i normally check the oil once a week, when I checked it before bearing spun, oil level was just above bottom line on dipstick, but then topped it back up, due to small oil leak Quote Link to post Share on other sites

TimD Posted May 31, 2018 Share Posted May 31, 2018 Tear the engine down, that should give you a good idea of what went wrong. Quote Link to post Share on other sites

5T4R7ET N/A Posted June 4, 2018 Share Posted June 4, 2018 If the oil was low and you went around a bend a little fast that could be enough to spin the bearing. Quote Link to post Share on other sites
