Hi, all,
So I'm probably about a 1/3rd of the way into replacing the head gaskets on my 2005 Super V8. I've removed the supercharger, the necessary coolant hosts, coolant crossover pipe, and power steering pump, A/C compressor and associated brackets. Wow... did the P/S and A/C brackets take time, probably took me 5 hours just on the pump/compressor/brackets.

I'm ready to tackle the crank pulley bolt and remove the pulley. I have the necessary specialty tools, but there's no way to get past the oil cooler lines to insert the pulley hold tool to remove the bolt.

Anyone know if I can disconnect the oil cooler lines and only lose a small amount of oil (what's in the lines)? In the Land Rover implementation of the AJV8 you can remove the oil filter and cooler lines and lose only a small amount. I have relatively new oil in the Super V8 and I'd like to not have yet another step, but I also don't want to have 7 quarts come out unexpectedly.

Also, while I'm removing the oil hoses, are there any gaskets (e.g., oil filter housing gaskets?) that I should replace? I'm replacing all the wear parts I'm coming across (e.g., just ordered new knock sensors after discovering my existing sensors have cracked housings).

Thanks in advance for any thoughts,

if it’s like the 308 setup i wouldn’t bother and just drain the oil

 

I worked on my crankshaft pulley some weeks ago and therefore had to disconnect the oil cooler lines. I was curious how much oil would come out, so I had a big bucket ready to catch whatever comes out but - kind of a disappointment, only a minimal amount (approx. 100ml) of oil was in the cooler lines and had to be catched. Good luck with your ones

 

Thanks, Hendirk, for the information.
I ended up draining the oil. I thought about it and while my head gasket leak is manifesting as a pressure leak (pressure in the cylinders escaping to the cooling system under load) it is possible there is some coolant in the oil so to be safe I decided to just change the oil.

Now my new challenge.... my 1/2 inch breaker bar might not be up to the task of the pulley bolt! I'm going to put some heat on it (via induction heater) and try again.

Thanks all - scooter
