Thread: Problems with Prothane Mounts......

Matter of fact there is one difference from my B14. On this car I removed some pad that sits between the oil pan and the cross member it's rectangulal and has 2 bolt holes. I wonder if this is causing my problems?

I can push on my engine as hard as i can and it wont move, and when i rev it, it doesnt move, but when i drive, it feels like the engine is picking up and dropping, like it does when you have a broken motor mount

Yes this is the same phenomenon that is happening to me I need to solve this issue quick because I have import wars coming up next week I will not race the car with the motor hopping like this. Hey did you remove that pad on the crossmember as well I am curious?

exactly. i have mad wheel hop.

So I'm just curious, what kind of movement are you feeling? And how/where are you feeling it? It could be other things rather than the engine, with my prothanes there's still some degree of movement felt in the shifter, and that's normal.

And if you're missing any bolts, any any any bolts, get some! They don't engineer bolts to hold things on for you to ignore them, especially bell housing and motor mount. It can cause strange problems, and you might even have one of the bolts strip out the threads due to the increased stress of others being missing.

With my OEM b13 trans, I would get quite a bit of movement with the gear shifter between foot on gas/foot off gas. But that was the gearbox. When I upgraded to a B15 trans, using the same motor mounts as before (ES inserts), that movement went to almost 0. I'm guess your engine is fine (if you have all the bolts in!), the movement is coming from something else.

like the engine is almost bucking, but only when in gear. like youre on the gas, and u let off, and it feels like the engine is buckin

Feels where? Where is the feeling coming from? How are you noticing it?

like in the shifter, the trans, and engine. you know how when you are teaching a girl to drive stick, and she dumps the clutch for no reason at like 1000 rpms, and the whole car bucks? like that.

sounds like you're describing what me and Isfahan talked about earlier, which is normal and comes from the gearcase. As far as the 'bucking' you described here, that sounds like operator error or something loose not engine-related if you've got your mounting system up to par.
