i have 3 problems with my z that i would like to fix before the good weather comes.

First off, i have a bad oil leak i am pretty sure its the intake manifold, i had that fixed by an excellent mechanic and its still leaking he thinks its still leaking and will fix it at no cost. when i had my tranny rebuilt i had the trans technicions change the rear main seal. still have this oil leak. i just want to make sure its the intake again. if the car sits for a day or more there is a 5 inch spot of oil on the passenger rear side. the whole under carrage is pretty oily. could it possibly be comming from somewhere elese? like valve covers, cracked head or block (i dont know)

engine has 50k miles on it no hesitation problems engine runs strong and is on synthetic oil

second problem the shifter button is hard to push down when cold to get into drive. trans technisions said it was the brake switch and replaced it for 50 bucks. still has same problem they told me to take to dealer because it may be the shift **** itself.

last but not least i have a clicking noise coming from the drivers side wheel i notice it the most at highway speeds and when i turn left but when i turn right it kind of goes away. it still does it if i hit the brakes. im thinking of either wheel bearing or tie rod end but im not sure
i am sorry for the long post but i want to get these things fixed since last year. Your help is greatly appreciated
Thanks, Frank

 

well i had a better look at the oil leak and the front of the manifold is wet where it sits on the block couldent really tell much of the back but i did notice the block on the drivers side is wet but the head is dry (from the bottom) and on the passenger side it looked like where the head was mating to the block was a little wet but above was dry on the head and below on the block was wet . could the head gasket(s) be leaking oil out. i never thought this was a problem on the lt1s

 

As far as your oil leak question check by the timing chain cover were it meets up with the oil pan.It might be leaking there and spreading further back onto the block.

 

as far as the front of the engine it is wet where the intake mates to the block to as far as the bottom of the timeing chain cover. i am explaing it the best i can. sorry

 

You might try cleaning it up a bit so you can actually tell where its coming from

 

is it possible that both heads are leaking at the gaskets or is it the intake leak from the front woking its way back when im driving?
