Please read and Please help!
Okay heres the scoop. I have a 93 Laser n/a. It ran great but around 90k it aquired a rod knock. I purchased a 6-bolt JDM block/head/5-speed from a reputable site trough ebay. Block had between 35-45k and had 6 month warranty. I will list what it was advertised to fit once i find the papers tonight, but i e-mailed the seller and asked "will it fit a 93 laser?" and he said yes
I then pulled the motor
and started swaping the accesories from one motor to the next - replacting gaskets, claning this, fixing that. New motor was Pretty clean all around
Well the motor was ready to be put in:
Instantly had problems. First off, from the exterior, there were noticable differences from the two transmissions (I replaced mine because it grinded first and second) Everything bolted up as it sohould, but the lines on the outside of the case were different, and it had a few different mounting points that the orginal one did not. Upon mounting the motor, we soon realized that it was not going to happen. With the right side, front, and back mounts in place (tranny mount not bolted up) the motor looked like this:
The hood would not shut, the IM hit the bottom of it.
This is how far off the tranny mount was:
Look how far off the bolts are from the holes in the frame. We managed to get all 4 mounts bolted up, but it vibrated soooo bad, and the right was puched forward and the left was ushed back, deff not right.
(we have since welded the mount where we wanted it)
I used the OEM mounts that were on the orginal motor. Everything else bolted up just fine.
WHY???????? Anyone know?????????
- Upon starting the motor once it was "semi" bolted in, we ran into problems. It was my mistake to not replace the water pump before the motor was put in. The gasket was rock hard and leaking. After replacing that, the oil pressure guage was going crazy. We traced that to a faulty sensor and fixed that. The cam seals were leaking, so we changed them out aswell. They to were rock hard (a sign the motor had been sitting around for awile) Both cam gears were wobbling, and one even broke (while motor was not running thank god) i simple pushed it to see if it was loose, and it broke! There were about 10-15 other probles we ran into, but i cant remember them all there were so many
.
- a 1G DSM is one hell of a good looking car - so why not fix it up ehh?
$1,200 maaco paint job - OEM green paint with added gold flakes - came out VERY good, people comment me on it all the time, very clean - i got lucky
- Car was in storage from november to april - gota love NY weather
- Okay back to the problems - because this car has lots of them. So once we got it running for the summer, we instantly had problems! What else is new? New radiator was in need. Put that in and it was still burning/leaking antifreeze. I couldnt find where it was going, it didnt drip on the ground, but was eating about 1/2 a quart ever 100 miles. It ran OKAY, and i didnt see any white smoke. IM gasket was new and pluges looked fine. After giving up i brought it to the stealership and they did a complete leakdown test. Turns out i have good compression, and my head gasket was good (to my amazement) Once the cooling system buit up pressure, there was a pin hole leak under the thermostat housing, and once it hit the block it would burn it - thus leaking antifreeze w/o driping on the ground. Well that was fixed and i know i have a solid motor., and also know im an idiot for not seeing that
- The orginal motor mount job HAD to change - so we did the fallowing:
We bolted the right side mount with a new poly mount. We then leveled the motor, centered it in the bay and welded thet f*&#er to the frame
We have the front mount bolted up, trany mount welded, and right mount bolted up. Problem solved ehh? wrong. Vibrates like a bi***!!!!! i figured it would, but not this much
- My power steering pump then shit the bed
- Okay long thread, but theres alot to this car. Here are the questions:
1. When starting car, it idles right at 1000 rpm's. Isn't it supposed to go to like 1500 then 1400 then 1300 etc. until it warms up? When warmed it idles just about 1000rpm
2. Why does the idle fluctuate? crusing at 50mph in 5th and push in the clutch it will drop to about 500, almost stall sometimes, then go to 1000. Sometimes randomly go up to 1200? wtf?
3. Motor mounts not working....
4. No power!!!! Seems to me that it is low on power, when you punch it the balls that is once had have shrunken severely. When reved in upwards of 5500-6500 rpm it just seems like it doesnt do anything but make noise
I searched around a little bit and have found the only difference in the JDM vs. USDM is the IM. I only bought the block/head so i should have no differences correct?
ANY insight to why my motor is not running correct, and doesnt fit my car would be great - i am at a loss at this point and so is the dealership - they are stumped Thanks!
