phipck Posted February 26, 2012 Report Share Posted February 26, 2012 sounds too tinny to be an internal sound, more like something touching the engine? loose bracket or something like that..... fingers crossed at least! Quote Link to comment Share on other sites More sharing options...
liner33 Posted February 27, 2012 Author Report Share Posted February 27, 2012 It was a loose bolt that had ended up inside the water pump pulley , general consensus is that its one of the bolts that hold the cam cover on but none are missing , cant find any other holes anywhere so i suspect when the belts were done about 1000miles ago they dropped a bolt and couldnt find it so simply found a new one  Quite how it managed to get inside the pulley must have been a 100/1 shot but it was certainly a worrying time Quote Link to comment Share on other sites More sharing options...

liner33 Posted April 12, 2012 Author Report Share Posted April 12, 2012 Bugger  Had a very slight noise from the car when cold traced it to cyl 4 so did a health check  Compression results (cold)  Cyl 4 = 160psi Cyl 3 = 170 psi Cyl 2 = 165psi Cyl 1 = 168psi  Leakdown @ 50psi (cold)  Cyl 4 = 16% Cyl 3 = 2% Cyl 2 = 2% Cyl 1 = 8%  Most telling was borescope pic from no 4 :shake:   Compared to No1  Quote Link to comment Share on other sites More sharing options...

liner33 Posted April 16, 2012 Author Report Share Posted April 16, 2012 Took the pics down thanks to haters on the MLR forum  Suffice to say its goosed , piston is damaged and has scored the bore and the head is damaged  Its borderline repairable but may work out cheaper to fit a later engine  If its repairable then better pistons and rods will be fitted which can support 500hp or the later engines can support 420-430 safely so its not all bad Quote Link to comment Share on other sites More sharing options...
Tango Posted April 16, 2012 Report Share Posted April 16, 2012 Was it a piston ring that broke up or a broken piston? Quote Link to comment Share on other sites More sharing options...
liner33 Posted April 16, 2012 Author Report Share Posted April 16, 2012 Damage from some time back before i owned it it mustve detted and broke the tip from the spark plug which then rattled around the cyclinder  Eventually the piston started to fail and was just starting to leak under the top ring  Only issue was a rattle (piston slap) when cold but didnt sound bad at all and was fine when hot  Still hit the 150mph and 386hp like this so high hopes when its run it Quote Link to comment Share on other sites More sharing options...
liner33 Posted May 15, 2012 Author Report Share Posted May 15, 2012 Ok long overdue update  I had a tapping noise when cold since i bought the car three years ago , since these are rattly engines when cold anyway i didnt really worry about it as it went within seconds as the car warmed up and the car always performed well, i'd changed the lash adjusters and oil a few times of course  Following the MLR 30-130 where the car again performed faultlessly i decided to give the engine a good health check  Compression results (cold)  Cyl 4 = 160psi Cyl 3 = 170 psi Cyl 2 = 165psi Cyl 1 = 168psi  Leakdown @ 50psi (cold)  Cyl 4 = 16% Cyl 3 = 2% Cyl 2 = 2% Cyl 1 = 8%  So whilst the compression results were ok the leakdown called for further investigation and a borescope confirmed damage to number 4 piston  Car was driven to Autotorque (Still drove perfectly) for Chris and the team to remove the head and check the engine  Damage was found to the piston and head but more importantly the bore was slightly scored, the damage probably occurred before i bought the car and gradually got worse over time  The decision was made to fit a low mileage Evo 8 MR engine rather than go forged . Someone contacted me as he knew of a good engine for sale from a well known MLR car that had met a grisly end  So a 46k 8 mr engine from a fq320 was delivered to Autotorque   As well as fitting the engine and swapping all my bling goodies over Chris gave it a full service and also changed the oils on the transfer box, gearbox and diff . He fitted some new superpro bushes to the diff mounts as i had a knock on gear change and they were found to be a little worn and also powdercoated the north/south car and cross brace while they were off.   So all back to normal   I got Chris to swap over the injectors and throttle body so mapping would be more straightforward and after a few logs i upped the boost a little to take advantage of those stronger rods and its happy as could be , probably got that magic 400/400 now but saying that my old engine did 390/390 with a damaged piston so perhaps its a little more Quote Link to comment Share on other sites More sharing options...
Rich Posted May 15, 2012 Report Share Posted May 15, 2012 Brilliant update, glad it's all sorted now. When you putting it back on the roller to see what it's got? Quote Link to comment Share on other sites More sharing options...
liner33 Posted May 15, 2012 Author Report Share Posted May 15, 2012 Probably next month , might do some on road tests though i have a program which can calculate the hp and its pretty accurate Quote Link to comment Share on other sites More sharing options...
liner33 Posted June 22, 2012 Author Report Share Posted June 22, 2012 Time for a change i think , while the car was away having its new engine i didnt miss it and have hardly driven it since its been back, did give it a good clean though and a coat of rainforest rub with is the first Dodo wax i've liked  http://www.pistonheads.com/sales/3998338.htm    Quote Link to comment Share on other sites More sharing options...
