mdturner Posted January 6 Share Posted January 6 L28 Engine sitting too high in engine bay after rebuild and install. Swapped auto to manual T5 transmission but it aligns and bolts up fine. Any help would be much appreciated. Quote Link to comment Share on other sites More sharing options...
calZ Posted January 6 Share Posted January 6 What do you mean by too high? Is the valve cover hitting hood or something? Quote Link to comment Share on other sites More sharing options...

Yes , it is hitting the intake throttle body. It is the same motor mounts, same block, no changes other than transmission swap to T5 , rebuilt front end, and the addition of the new Protunerz intake.

Did you use a different lower transmission mount when you swapped the automatic to T5; and if so, did it change the overall angle at which the engine/transmission sits? This could possibly make any components "forward" of the engine mounts sit higher in the engine compartment (relative to their original position). Can't think of any other reason why you'd have clearance issues now, vs no issues before the swap. Quote Link to comment Share on other sites More sharing options...
calZ Posted January 6 Share Posted January 6 That was what I was thinking as well. The only thing that has changed is the transmission, and the only thing the transmission can change about engine mounting is the angle. 1 Quote Link to comment Share on other sites More sharing options...

The valve cover is hitting the intake throttle body? Not sure what the effect is but sometimes people get the left and right engine brackets switched. I know it changes the angle of the engine. Not sure about height. Parts 6 and 7. https://www.carpartsmanual.com/datsun/Z-1969-1978/engine-280z/engine-mounting 1 Quote Link to comment Share on other sites More sharing options...
mdturner Posted January 7 Author Share Posted January 7 I beg your pardon, I meant to say that the hood is hitting the intake throttle body. I have added pictures below, in which I hope you can see my problem. Also, I have taken pictures of the motor mounts as well for comment. I used the transmission mount off my parts car but, when looking at it again, it is no different than the original mount for the automatic transmission. I knew the tranny mount was supposed to be different and assumed, when it bolted up correctly that it must be the right one. I will search for some pics of the manual transmission mount to compare. 1 Quote Link to comment Share on other sites More sharing options...
NewZed Posted January 7 Share Posted January 7 Can't tell from your pictures if the brackets are swapped. The engines have a tilt to them with proper installation. If the brackets are swapped I think that it does bring the left side up, making the top of the valve cover more level. It can look correct but be wrong. The simplest way to tell might be to check the bottom of the oil pan. It should be level from left to right. Hate to say it and maybe, subconsciously, you already know it but it looks like that custom intake manifold could also be the problem. Where did it come from? Good luck. 1 Quote Link to comment Share on other sites More sharing options...
mdturner Posted January 8 Author Share Posted January 8 The intake is from Protunerz and they tell me there should be no modifications required. I’ve seen many L 28 with this intake on it and never read any mention of a modification being necessary. Quote Link to comment Share on other sites More sharing options...
madkaw Posted January 8 Share Posted January 8 What year Z ? what trans crossmember ? Is the crossmember the early or late ? If the crossmember ( late ) is put in upside down that would lower the rear of the trans and raise the front of the engine . Quote Link to comment Share on other sites More sharing options...
