    Depending on the extent of the damage, yes.

    Got it on a stand, pulled the crankshaft caps.. and found that cylinder 2 rod bearing was toast.




    Tomorrow, I will pull the crankshaft and get it over to a machine shop. Once it is machined, I will order the proper bearings and a replacement rod and cap.

    How many miles/km's did it have when it let go? I was about to pull the trigger on one, but got worried that near 100,000km was too many miles for $3750. I hear G&R Imports has good prices on parts and replacement engines.

    It has somewhere around 52,000 or 53,000kms on it.. (I pushed the chassis outside, and I do not feel like going out to look exactly). The issue here was that it was not well maintained.. the last oil change before I received it was about 4 years prior.. even though it had only driven about 1000kms. I also was traveling about 70-75mph with the engine spinning at 6000rpm.

    I have been in communication with G&R and Twin Rivers here in the states, as well as Yokohama Motors and JapanParts.com to source various parts. The only quote I received back was for a replacement crankshaft with bearings at $850 (!!!) plus a $300 core (and core is graded as well) from Twin Rivers. I guess $150-200 for machining and $170 for bearing kits is a much more palatable option.

    Today the crank is out. I have it wrapped up in bubblewrap to prevent more damage, and I will bring it to the machine shop tomorrow.


    I took the head off as well today. Cylinder walls look good, no gouges or visible cracks. The head gasket was also fully intact.


    The head looks okay as well. No valve damage or anything of that sort. I will have it cleaned and pressure tested. I will also have the block cleaned. I measured the head, it is 28cm from one end to the other.. just over 11 inches!

    After looking at the pieces a little more, it appears that the #2 piston made contact with the head. I am not sure if it just broke the seal of the headgasket or if it cracked the head, but that does explain why the cooling system pressurized and pushed out a bunch of coolant. As such, I no longer trust the head or the piston. I bought today a new head, piston, and a brandy new crankshaft.. as I found one for not too much more than I can have my old one machined for.

    This engine rebuild is beginning to get quite expensive.. but I should not have any more issues for a very long time.
