random question on the 3.4l dohc
#3
Yea, I don't know about loving it. Every mechanic I brought my 95 Z34 to said they hated working on that engine. The last guy said "oh no not this peice of $hit" for which I said don't worry about it and went somewhere else.
Ever try changing the spark plugs and wire set? Very big pain.

yes i have tried to get the plugs, i enjoyed working on it actually, the only 2 things that were a PITA was how time consuming it was for me, and then at the last bolt to get to the rear plugs, i didnt have the right socket aaaaaarrrgggghhhhh!!!! other then that i enjoy working on the car lol.
if anything the brakes/tires are giving me more issues.
bolts locked up
cant fit new pads in
studs breaking
studs stripping nuts
lots hub caps
yup big PITA

Anyone who can rebuild engines can rebuild the LQ1. The bottom end is no different than any other motor. It uses a similar block to the old 2.8 and 3.1 V6 motors. You can have the heads redone too, there isnt much difference between the LQ1 heads and any other DOHC head. The engine itself is a good motor. Its just hard to work on. Most people I hear complain about it seem to just be too lazy to spend the extra time to work on it. Its no less reliable than any other GM V6. The main killer of these motors is poor maintenence. Not changing the timing belt being the biggest. Running it low on oil being another big one.

I absolutely love my lq1 heavy duty reliable if kept up with. powerful, and that growl is just amazing

Yeah my oil pump drive gasket is starting to go. Will need to do that soon. Its still an ok trade off for not having to drive a mobile BBQ grill. (Sorry 3800 guys lol).

Water pumps on the LQ1 arent any more prone to failure than any other GM V6 and are incredibly easy to change. The only issue with the timing belts are when people neglect to change them or dont do the job correctly. And I think the biggest reason there arent many 5 speed LQ1 cars left on the road has more to do with the rarity of the car than problems with the motor. They only made 5 speed luminas and grand prix with the LQ1 from 91-93.
