Timing Chain cover removal.

Timing Chain cover removal.
So the water pump finally went bad on my 96 gxe. I removed and replace the water pump while reading instructions from the "how to" sticky from Ilyak. FYI it was an extremely good write up!! but while i was removing the timing belt tensioner to replace the water pump i lost the spring and piston from the tensioner into my timing belt cover...... some how i was able to fish out the spring with a magnet but the piston just wont come out. so my second option would have to be to remove the timing chain cover and physically remove the piston. i was wondering if someone could give me some sort of direction on how to go about doing this. so far, everything necessary for replacing a water pump is removed along with the passenger side motor mount and all the 10mm bolts surrounding the timing chain cover.

i wouldnt leave anything loose by the timing chains. if it binds or gets caught kiss that engine goodbye. take my advise do it right the first time. find the missing part and take it out. the cost of a tube or two of form a gasket to put the cover back on is ceaper than a motor. ( however i just scored one for 175 bucks lol...

i believe i read on this forum somewhere you have to pull the oil pan in order to remove 2 bolts for the cover itself that may be your only draw back you can pretty much see all the other bolts and their easily accessible and you also have to pull the harmonic balancer and replace the front crank seal

aww man that sucks. im sorry. but maxed out 99 is correct, you have to drop the oil pan to get to a couple of bolts holding the timing cover. as mentioned before, the crank pulley, the mount and mount bracket, theres a few bolts in the middle of the timing cover iirc. and then splitting the timing cover can be tedious...good luck man.

soooo....my dad is an engineer and designs ultrasounds for a living, he brought a long thin flexible tube with a tiny camera connected to the end which was hooked up to a laptop, we shoved it down the hole where the timing tensioner is. Took some time but we finally found the piston, picked it up with another flexible tube connected to a super strong magnet!! YAY! everything is in perfectly working condition now, THANKS FOR THE HELPFUL ADVICE! i still cannot believe how lucky i was.

The first time I ever pulled a cover I forgot about the bottom bolts, and sat there for a good half hour trying to pry on the cover and whatnot until I had that "Wow, I'm dumb" moment.

Chiltons will not show the 2 Timing Chain cover bolts !

High level steps...
1) Drain oil and coolant. Remove the oil pan and remove the two 10 mm bolts on the Tire side of the oil pan that go up into the timing chain cover. Note Chiltons manual will not mention these two bolts. Put the oil pan back in place.
2) Remove fan belts for AC, pwr steering and Alternator
3) Disconnect the AC compressor and alternator. Note, I did NOT remove them just removed bolts that mount them to the engine. I then supported them via a jack stand.
4) Remove any sensors or wiring harness mounts on the time chain cover
5) Put a jack and jack stand under the engine oil pan and then remove the passenger side motor mount. Note, the motor mount is like a rubics cube, ie many pieces. Note, you can leave the large bottom stud in place. The cover will slide over it.
6) Remove the timing chain cover bolts, note Chiltons indicates a preferred sequence to remove them.
I only pulled the outer timing chain cover.. And did not see a harmonic balancer on my old lady, ie 1995.
Yes there are two rubber gaskets. One is round and slides over crankshaft after you have the timing cover in place and before you put the crankshaft pulley back on. The second rubber gasket is U shaped and fits on the bottom of the timing chain cover.
Note, I replaced the water pump, chain tensioner and main chain guide while in there. On my old lady the Chain guide and tensioner had been updated by Nissan.
Hope this helps...

AWESOME!!! Pump is out. Jsutter thanks for the reply!!Well after removing power steering pump, the timing cover was easily taken off. Well my guess was right. Timing chain decided to jump a few teeth and hang around with a different set of teeth freinds..
Going to Set piston #1 to TDC align cam sprokets and hopefully when i bolt it back together this baby starts..Thinking of doing a how to vid. Shot out to jaaaaaaaaay sutttaaaaaaaaa!!!! woot woot!!
