Did all of my timing guides and tensioners and for the life of me I can't get this damned lower timing cover installed. I tapped it in place with a rubber mallet but it pushed the head gasket back. Anyone have any tips for installing the lower timing cover?

When they did mine at T3, they actually pounded the oil pan lip downward just a little to make more room. He assured me it would come back up fine when they tightened the bolts - and we're on 9 years with no leaks.

I believe they also removed that intermediate cover on one side that fits above the head gasket. He also coated the portion of the head gasket that sticks out with RTV during reassembly.

Good luck!

I'll give the oil pan method a shot tonight, thanks!

Oil pan method worked great, but there was still one bolt I couldn't do, so screw it, everything but that one bolt is on and put back together. Also started the install of my taurus fan and external trans cooler.

Good luck... take pictures of your fan installation please - although putting anything Furd under the Q's hood seems wrong at some level :D

the first gen nissan quests where made by ford using a mix of nissan and ford parts including the Efan on it that uses the taurus fan motor, but a different shroud and fan. So I'm thinking it shouldn't place the ford curse on my Q, as for the install it's nothing special, running it off a toggle until I can build a controller.

Update: got around to finish installing everything and drove it around the block to find it leaking between the upper and lower timing covers. I thought I would be ok, as only one bolt per side was missing, I guessed wrong.. :gapteeth: The HG is soo close, but I can't think of a way to push it out so I can get a bolt through it, that and I REALLY don't want to pull everything back off and pull the timing cover for the 4'th time. I am half tempted to pull the plenum, valve covers and upper timing covers at this point.....
