Thanks | | | 03-23-2005, 11:05 PM | #4 | Member Join Date: Mar 2005 Location: Rimini, Italy (Europe) Posts: 73 | Hello, my M42 have approximately 190000 km ----> 120000 miles the valve retainers is hydro lift, I think that at 180000 km the 16 hydro lift they must be replaced because they emit a sound....a bad sound! especially with cold motor... If the game of valve is wrong, the flame of combustion one extend within the culverts of aspiration and drainage... therefore the valve are burnt!!!!!! at 180000 km I think that it is better to replace also a chain tensioner... this in european motor whit 95 ron unlead however this is a good motor, the max speed at 175000 km has been 225 km/h -----> 140 Mph very good! excuse my english... __________________ I'am italian! | | | 03-24-2005, 12:10 AM | #5 | I miss my Ti....... :( Join Date: Nov 2003 Location: Los Angeles, CA Posts: 828 | I know the feeling.

Do a good rebuild and you will not have to worry about it again. -Chad | | | 03-24-2005, 12:24 AM | #6 | Member Join Date: Mar 2005 Location: Rimini, Italy (Europe) Posts: 73 | ok, thanks, but I have a question: after you have replacement the 16 valve, whit old piston rings and new valve, the oil consumption was excessive? before, my M42 like a 1 litre of castrol oil every 3500 4000 km............ __________________ I'am italian! | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | Similar Threads | Thread | Thread Starter | Forum | Replies | Last Post | Problem with quick reply | schussey | Site Feedback | 2 | 10-12-2004 03:12 AM | |
