| LT Front Oil Seals Replacement |
Subject: LT Front Oil Seals Replacement by PLRX on 2011/1/9 6:10:34 I did this few weeks ago- Since my rebuild, I had a small oil leak. Yes, it was/is from the infamous LT1 location. This engine has 8,000 miles since its rebuild. Started with draining the Dexcool and yes, I made a heck of a mess After I remove the basic; air ducts, disconnect all plugs it was time to remove the Camber Brace. If you have one, you know how delightful it can be.

H2O Pump out  This is the H2O pump oil seal. I installed it wrong to begin with. I did it wrong on my 95 3 years ago and I did it wrong in my 96. I did not use the special tool, if you dont use it, the seals bends backwards and it doesn't seal...duh!  You will wonder why I dont get the balancer out of the way. The LT4 balancer is thicker that all others LT engines and to remove it completely, you have to loose the rack & pinion. I was not going to do that today.  LT engines 92-96 Cancer  Obviously the Opti oil seal was leaking oil.   The J39087 Special Tool. "Shaft Front Cover Seal Protector"   New H2O Seal  Don't forget to install the new O-Rings for the H2O pump's shaft and the Opti's shaft.  Oil Seals Installed, no RTV. Yes, it was a PITA to do it with the engine inside.  I've done this few times, I got the opti in at the first intent. YEAH Baby--  The balancer is back up, tighten 3 bolts to 63 lbs ft.  the H2O pump was installed and torqued to specs.  The Camber Brace would not fit, I had to raise the Vette at the crossmember for it to "stretch" and for the shim to fit.  Water hoses and connections up.  Fill up with Dexcool, bleed system and test drive.  |
