                    Have you got the 2 bolts that are inside the gearbox bellhousing?

                          The project moves on this weekend!! New bearings has arrived and some plastiguage!

                          I must say that my engine is really nice inside.. the only piston that had small ping marks was the 5th one..



                          No feelable tdc marks in the cyls which is good, also a nice cross hatch pattern and now glazing at all

                                The job is done and the engine is started! Also found the problem to my rough idle The ISV and After run pump connectors was in wrong place I guess.. the ISV cables are brown and something and the after run is red and white ?
