Team Idris Posted April 27, 2012 Share Posted April 27, 2012 The timing cover doesn't seal to the block without silicon sealer? You're old cam might be in the sump, so worth looking? You're old cam might be in you're relief valve, so worth checking that too! Which is what I learn't from my 3.5 rebuild Quote Link to comment Share on other sites More sharing options...
moneypit Posted April 27, 2012 Author Share Posted April 27, 2012 She is running quite well at the moment but with the usual tick tick tick and low on pwer , all exhaust gaskets ok and compression down on No 7 I decided to do the cam as she is currently sitting at 270K so I think well due for the change .Results of the compression test as follows Cyl 1-181 psi Cyl 2-188 psi Cyl 3- 174 psi Cyl 4- 174 psi Cyl 5- 188 psi Cyl 6-174 psi Cyl 7-145 psi Cyl 8- 174 psi I am hoping that No 7 is down on compression because the cam lobe has worn down and its not a valve but will find out soon enough I have no past history on any maintenance done so would rather do it all now and keep the wife happy with her run around. For the gasket I have some tiger seal which works really well. Its a US import into Poland and runs on a closed loop LPG which was installed three years ago (Probably washed the valves clean as a whistle) .Her saving grace is there is not a single spot of rust on her and is generally in good shape so worth the investment.

moneypit Posted May 6, 2012 Author Share Posted May 6, 2012 Hi All Cam change done and all went well .Before the change decided to give the exhaust a full check and found a leak on the LHS cat but went ahead with the change any way .Lucky I did because the chain and gears were well worn The rockers were very dirty and showing signs of wear on the shafts so thats next on the list although wished I had bought them in for this time The cam showed less signs of wear than I expected but the cam followers were shot completly photos to follow. and the reassembly went of with out any problems The cam installed is a pipercam Torquemax and I can definetly notice an improvement on acceleration and shifting along with a lower RPM at cruising speeds so well worth taking the time to do it .But all this has done is wet my appetite to get a donor motor and do a complete rebuild with a possible power upgrade .I think I start some looking around for a donor and see if there is anything available.
