      OIL LEAK - 1994 Cutlass LQ1

      By GnatGoSplat · Posted

      I've never used that product, but I'm generally not a fan of stop leak products.  I've used them in the distant past.  In my experience, they tend to cause more problems down the road.

      OIL LEAK - 1994 Cutlass LQ1

      By bluecalais79 · Posted

      Thanks I will check that out. I did buy some of Bar Seal's best stuff and already it seems to be working. I'll know more about that in a few days. There was coolant on top of the hold down bolt (for the oil pump drive) and moving on down that way. But, I cleaned it all off before putting in the bar seal, followed the instructions and then drove the car a bit. No leaks last night and no leaks this morning, it's all dried out. Hopefully this will be the end of that, but I will keep my eye on that fitting.

      1997 to 1994 Grand Prix subframe and suspension conversion

      By ceaspaece · Posted

      Picked up a 1994 Pontiac Grand Prix coupe a few months back for a good price. Im in the process of putting a new motor in it due to an oil pump failure. But I've been thinking about suspension and steering system modifications. There isn't anything available for the 1994 but there's a ton of support for 1997+. Due to differences with the control arms I figured that easiest way to retrofit would be to swap a subframe from a newer Grand Prix into my '94 but I'm not sure if that's possible. From looking up photos online The general shape and mounting position seems to be the same. I was just wondering if anyone's ever done this swap before to update the suspension and steering because I'm sure anything's better than the cartridge strip design in terms of performance.

      It should retract.  Almost seems like it could be getting bound on something as you said it drops slightly below the close point. You can check for it getting mechanically bound by removing the fuse and connecting a multimeter in Amps mode in place of the fuse.  When it stops moving, see if it's drawing any current.  If it is, the motor wants to move it, but it's getting mechanically bound.  If no current when it stops, then a switch or relay is electrically preventing it from moving further.

      OIL LEAK - 1994 Cutlass LQ1

      It's possible coolant can leak from the intake manifold if they messed up the install somehow, but it's also possible it could be the heater hose quick-connect fitting.  That's another source of coolant leaking from around that area that I believe is a fairly common issue.  Especially more likely since they had to disconnect the fitting and probably didn't replace the fitting.  It's this part: https://www.rockauto.com/en/catalog/oldsmobile,1994,cutlass+supreme,3.4l+v6,1223367,heat+&+air+conditioning,heater+hose+connector,6876 It's located right above the crossover pipe and you might see evidence of coolant having dripped on the crossover pipe shield if it's leaking.  I would put a white cloth under it and see if it gets wet.
