I am refurbishing my old alternator which most likely failed due to worn out brushes; however, just to make sure, i am testing all the inner components: the rotor, stator and rectifier. Testing the stator and rotor was pretty straight forward but i found testing the md133171 rectifier...

i have a "second hand" 6-bolt 4g63 engine which came with a timing belt cover stamped with part number MD141459 S / MD141461 B.this particular timing belt cover leaves about 1/2" gap between the oil pan flange and the bottom end of the cover. the timing belt can be clearly seen thru the gap...

After installing a brand new timing belt and putting on about 18000km, i noticed the timing belt started making rhythmic 'swooshing' sounds as if the belt was flapping and rubbing against 'something' so i took the timing belt cover off to examine the belt and instantly noticed irregular shallow...

i am struggling with the removal of my mid-section of the 3pc spoiler on '94 talon. i am trying to be as gentle as one can be as not break any clips. Number of members on this forum struggle to find replacements for broken clips so i dont wish to join the crowd.in any case, there are posts...

Why would "coolant temp", "charging" and "brake" warning lights come on at low intensity? Sometimes these three warning lights come on and are very faint, then they turn off, then they come on at 3/4 brightness, then they flicker and/or go off again. When i lift the hand brake and the "brake"...

I have started blowing the 10Amp tail-light fuse for no apparent reason... the result is that my dash and instrument panel/cluster has no lights. The radio has power and lights work. The tail lights dont work.From other posts on this forum, my understanding is that the dimmer switch in...

methinks this engine is not running right bc it sounds as if one cylinder here and there misfires. it shakes a bit when idling but picks up when it revs higher. it lacks a bit of power when i drive it. i cleaned up and re-gapped spark plugs, same with plug wires, my injectors are working...

Very odd situation... I drove the car last summer, parked it for the winter, wanted to drive it this summer, tried to start it just now,... no spark. Started tracing the problem. Noticed my CEL was not ON. Accessed resources you guys graciously provided over the years here. Found this post...

This used to be FWD 1990 Laser M/T, 4g37, n/t, no ABS, no A/C, no C/C, etc. I swapped the 4g37 out for 4g63. The donor was a 1992 Eagle Talon, FWD, M/T, 6bolt 4g63, n/t, A/C, C/C, no ABS (I believe = 99.9%). I did a bit of electrical work to make the swapped 4g63 run. I got a lot of help...

I was replacing the stock stereo/tape deck with a better set up and forgot there is always one live wire to feed the clock and blew the 10Amp "room", NOT the "radio", fuse. No interior lights worked after that. The interior lights started working again after I replaced the fuse. Also, I did...

This is a '90 FWD plymouth laser with access to fuel pump underneath the car on the back side of the fuel tank. After removing the 6 self-locking bolts/screws from the flange, the fuel pump came loose from the fuel tank flange, about 1/4", and no amount of twisting, vibrating, lifting...

I have swapped 1990 1.8L 4g37 for 1992 4g63 including tranny KF5M222VPZ / PA9159. I left the 1990 shift cables in. Now when I shift there is not enough travel/throw to fully reach 1st and 3rd gears (only half-way) but there's enough travel to engage 2nd and 4th gear. The whole offset of the...

I purchased main bearings, including thrust bearings, M136A 15H19A sizeSTD made by TAIHO in Japan for my pre-April 1992 6bolt 4g63. It turns out these bearings which NAPA lists as suitable for my block are too narrow. They are 0.840" wide as opposed 0.975" which is the size I need. My old...

I am in the process of replacing 4g37 engine with 4g63 n/t motor. I pulled the engine bay harness from a 92 Talon which was equipped with A/C and cruise control and installed the harness in a '90 laser w/o A/C or cruise. All connectors fit except two 4g63 connectors that have more pins than...

I am replacing a 6bolt crankshaft that crankwalked on me...see here: 6-bolt crankwalk - 0.065" endplayI have a replacement 6bolt crankshaft that I am not able to date, i.e. I cannot determine the date of the engine manufacture that the crankshaft came from. I am ordering all bearings and...

I have my motor bolted to an engine stand and planning to swap crankshafts. Do all you guys follow the Mitsu service manual step by step or do you have some unique, nifty, minimalistic and efficient ways to remove crankshafts to save yourselves some extra work and time?

I could not resist buying a 1992 n/t, 5spd Talon w/ 100K miles on it for $400. Lady owned since new and she kept all receipts since the day she bought it. The driver side frame was completely gone but the motor appeared to be in excellent shape. I checked the compression, 174 - 169psi hi to...

I am taking my 4g37 engine from a 1990 Laser and replacing it with a 4g63 n/t 6-bolt motor from a 1992 Talon. The '90 Laser has no A/C, cruise, etc. The Talon does. I already took both engines out and noticed that some of the connectors dont match up, i.e. the O2 sensor. I figured I might as...

I have dropped 2g head, including intake, on my 1g 7bolt block recently - '94 Talon, non-turbo, most likely w/ California Emissions ECU settings . I have also installed the 1g CAS, throttle body and EGR valve on the 2g head; among others. The timing of the engine should be 5 degrees BTDC +/- 2...

I took the cylinder head off, replaced piston rings and valve stem seals. While the head was off, I performed a combo compressed air/ valve hydro test to determine if valves were properly seated. They were. No leakage.Then I positioned cylinder #1 mid-way up so that 1/2 turn clockwise...

I have some used valves (see pics) and am completely uncertain which can/not be re/used. Gentlemen, your esteemed opinion would be much appreciated.Here are exhaust valves that were polished lightly with sand paper just to get carbon and other gunk off. The black rings are actually low spots...

I am installing 2g head on top of 1g 7bolt block. The head came off a donor motor. I dont wish to speculate re the history of this head/motor; however, I have visually inspected the head and tested the sealing of valves with the cams installed. This what it looked like after light cleaning...

is there a quick and dirty way to tell what i can get away with regarding a cylinder ridge at the top of the compression ring travel in order to put new rings on and not use ridge reamer?

Would any one here know how to perform a fuel pump test on a 1990 ECU (n/t) in a similar fashion as was done on various other components at this link: https://tinyurl.com/jummda7 ?Alternatively, how do i get on OK code that, at bare minimum, would indicate that the ECU is in good health...

i am trying to assess the general health of this mystery 6bolt ( https://tinyurl.com/hvh4pqr ) w/o taking too many parts off and cluttering further our family garage which already looks like it was taken over by a dsm car horder. the motor is on engine stand, spark plugs out. i am turning the...

my first look at a 6bolt i bought for parts. but since an engine i was going to fix blew up on me recently; as discussed here: https://tinyurl.com/jgpzvw6 , i am going to see if i can get this engine running w/o putting a lot of $ or time into it.so i took the timing belt cover off to check...

just bought a donor 94 eagle talon w/ 7-bolt 4g63 nt. the motor would start w/o hesitation but it would run extremely rough. it wouldnt idle. it would stall. the motor misfired badly. i had to keep the rpm above 1500 to keep it going. i took it for a short test drive, about 1 mile. even w/ a...
