I own several Toyota products and cannot be more pleased with their quality and lack of serious maintenance issues. I own the Service manual for each vehicle and use them for all maintenance activities. I found this site while trying to help a friend with his '92 Corolla. He has the 4AFE engine and has busted his timing belt @ 82K (yea he doesn't drive it much). It was severly dry rotted and just went. His mechanic is telling him this has caused his valves to be bent. I have gone to Gates and Napa site and each seems to indicate this is a non-interference engine. However, a quick call to the local Toyota dealer ship, the parts guy said it was in fact an interference engine. I have searched till I cannot search no more and cannot find a definitive anwer to this question on this site. I am sure there are experienced 4AFE DOHC engine gurus that can provide their view.
All posts and data I find state the engine is non-interference. If your friend is worried, rotate the cam by hand and see how the valve train responds.
he is talking about the 92 DOHC engine though.. maybe that one is interference? if it's a dohc is it still 4afe? i dont think so

DOHC or 4AFE or what it is I guess is some of my frustration. The car is at the mechanic and is on the other side of Dallas from me so I cannot confirm either the engine code or SOHC or DOHC. Just going by what by friend is saying. He did say the parts guy at the Toyota dealer inferred this was not a common engine and he told him he was sorry he had it. Thanks for all of your responses, but without solid evidence what he has I guess I cannot ask for any further help from ya'll.
if its a GTS it has a 4A-GE which is DOHC and has 2 valve covers and 2 timing pulleys for the cams and it IS an interference engine...
If its not a GTS it has a 4A-FE which is also DOHC but! it only has 1 larger valve cover and 1 timing pulley for both cams the intake cam is driven via gears under the valve cover from the exhaust cam this is NOT a interference engine..
