New to the site!

I did find a 89 Grand Prix in a yard a week ago but that's it.  Everything else seems to be 2nd and 3rd gen cars, especially Pontiac.  No 1st gen Cutlass or Regal.  I'm guessing they were all crushed long ago.  Makes me sad.

Thanks!  I like your ride as burgundy is my favorite color.  I don't know why I haven't mentioned this before but I use to have a 2006 Grand Prix GXP that was burgundy.  I wish I never sold it, bought it brand new and the V8 was quick!  My buddy use to have a 2001 Grand Prix that was identical to yours but was silver with black interior.  He had the same rims as yours and yes they are factory alloys.  I think they are more rare than the silver and chrome star wheels that most cars had so maybe you should keep them in the garage even if you swap to aftermarkets.  His car was totaled in a hail storm and he really misses it now.  Anyway, welcome and I've kind of rambled on here.

Wow, how'd I miss this thread?  I can't wait to see what it looks like after a good bath inside and out.  I have the weirdest craving to want to clean that car right now...lol.

 

Welcome to the site, excited to see the progress!  Any photos of the GMC you're working on?

I'm looking forward to really scrubbing her up!  Might have to have the interior professionally done since it's really bad but I think I can handle the outside part.  I have some extra time this coming Tuesday so I will get some pics of my GMC on here.

I just found this post on here despite me posting after these were made. Damn, I need to get on a computer more often...

 

Luckily the earlier LQ1s had a non interference design which means if the belt fails the engine won't be damaged, it just won't run. IIRC in 95ish they changed it to an interference design which will destroy the motor if the belt fails.

 

There's 3 versions of the LQ1. The 1st one is OBD1 compliant and doesn't have  a cam sensor IIRC, They were made from 1991 to 1993. The 2nd one that is ODB 1.5 and does have a cam sensor as well as other new sensors, those were made in 94 and 95 and the ODB2 compliant interference LQ1 which was made in 96 and 97.

 

1995MY was the last year of the non interference design. 1996 started a new plenum, removable throttle body and interference design.

 

I didn't know that!  Thanks for the info and for the reassurance.  Not sure they would change that if it threatens to destroy the motor.  Doesn't seem to make sense.  This is my first W Body so I have a lot to learn.

 

The change was to boost up power, not sure why or how making it an interference engine helped that feat and the sad part is that it was only for a 5hp and 5tq gain.

 

Ask questions and we can answer them. We're nuts for these cars sadly. I've said this in another thread but some of us have more than one W and some of us have only driven W since we got our licenses.

 

I sadly have 2 W's.... with the same engine which doesn't make it any better.

Thanks for the great info.  I would have never known any of this unless if I hadn't found this site.  So I guess having a early LQ1 is kind of good.  Less sensors and if something happens, the motor won't destroy itself.  My understanding is that early gen LQ1's are rare especially in the Cutlass cars.

Then if the belt breaks on a '93 LQ1 passing six grand the engine will not grenade ? That is really good to know. Since the service records show that the belt was changed fifteen years and 55,000 miles ago, I have been reluctant to take over four and feels like that is where it starts to go.

 

Guess 9.5:1 compression and .390" lift is enough for non-interference. Also the FSM indicate the belt is not "old" until past 70,000 miles.

Did get a Delco 1808A sender and will see if that makes the gauge show pressure and not just be a switch.

Yeah, this site is pretty good for LQ1 info. Only other place that would be a good source for LQ1 info is the Fiero forum, they like to use the LQ1 in their cars. I've actually seen one of em make a custom intake for their LQ1.

 

All LQ1 cars are rare now. Z34s, GTPs, Cutlass Supremes.

It shouldn't but there's always a possibility. Amistydj grenaded his 95 LQ1 engine redlining the hell out of his engine. Of course in his situation he had a bad pulley and that might have made a lot of difference in the situation.

 

I however also had this issue before (timing belt breaking) on my 94 and it survived even though it was hard as hell to time it.

 

TLDR, LQ1s usually don't grenade themselves if they don't interfere however it can always happen.

Playing around the engine bay of the International this morning and noticed that it has an aftermarket radiator cap on it.  I looked at the 89 International parts car and grabbed what looks like an original cap, not sure, can you guys let me know?  I don't know if they used different ones between the 3.1 and the LQ1 cars.

Aftermarket one.

OEM one I hope.

The first pic is the cap from a 95 LQ1 and I can validate it is original. The second pic is from a 91 LQ1. I can’t validate the 91 cap is original, but the rest of the car seems too be and it closely resembles the 95 cap, so I believe it is original. fb6feeabf33c3dbd4733f61d39933acf.jpg89e8e02ca527bfc6fd17ea44be09e890.jpg

Thanks again bud!  I'm going to keep the plastic OEM looking one, maybe there was a difference between the 3.1 and LQ1 cars and this is just an original 3.1 cap (off of my 89 International coupe 3.1 parts car).  I like it a lot better than the obvious aftermarket one.  I'm going to look for the ones you posted when I hit the junkyards in the future too.

MemphisMan has been helping me out lately with some things to look for on the LQ1's.  He's been great and I'm learning a lot.  Since I'm new to the game compared to a lot of guys, this may be boring but I'm finding it very interesting.  He suggested pulling the front bank cam cover to see if the belt is intact.  Things look good so far.  The car always turns over strong but not starting up.  I was wondering if the motor will turn over if the belt is broken, I have since learned that if the belt is broken it will still crank but seeing the belt intact is a good sign that it's ok for now.  I still think the fuel pump is the culprit but I want to get the dash working first.
