Hi everyone,
Completely new to the forum and hoping someone here might be able to help me.
My wife was driving the 2012 LR4 when it overheated. She pulled over immediately, but the damage was done. Failed head gaskets, confirmed by two reputable LR shops.
Same old story...Repair costs were prohibitive so it's either sell/part out or take on the challenge and fix it myself. The truck only has 85k miles on it, so I decided it was worth the work.
For someone that has never taken on a project of this size, I've found this to be a ton of fun and has really strengthened my bond with the truck.
Threads here have been incredibly helpful and the job has gone as smooth as can be, until time to reassemble the timing. Once everything was together, the crankshaft simply wouldn't turn by hand. Now, I was NOT going to put too much force on it and I've been very slow and easy when trying...was NOT going to force it. Something is awry.
When the chains and camshafts are out, the crankshaft turns by hand as expected. Nice and easy. No odd or unexpected sounds.
Reassemble all of the timing components, and it doesn't want to move.
At some point, I think I got the crankshaft out of TDC (almost certainly). I spent time finding TDC again, reassembled timing, same outcome.
Is there an obvious step here that I missed? Am I simply not getting to TCD and that's causing the problem? Or, are there other, more concerning possibilities here?
Appreciate any advice or help.
