I'm assuming it's fuel related, but my primary concern could be the timing chain. anyone familiar with the noises/sounds you'd primarily hear from a timing chain letting loose? I didn't hear any apparent engine noise during all of this, but then again, my crappy exhaust from the PO might have drowned anything out that I would have heard anyway. | | | 09-03-2008, 06:45 AM | #2 | Moderator Join Date: Mar 2007 Location: Maryland Posts: 3,220 | you might want to check your vacuum & the hoses its connected to. Check the valve cover breather hose also to make sure its not ripped like mine was. | | | 09-03-2008, 08:01 AM | #3 | Junior Member Join Date: Jun 2008 Location: Buffalo Posts: 8 | Quote: Originally Posted by BMW_Hatchback you might want to check your vacuum & the hoses its connected to.

The strange thing is I'm fine if I give it $10 of gas a day.... | | | 09-06-2008, 09:24 PM | #6 | Junior Member Join Date: Jun 2008 Location: Buffalo Posts: 8 | turns out it was the fuel pump. pulled the line at the filter, turned the key, no spray. threw a new pump in, runs like..almost a charm. except for the fact that somehow, maybe from cranking the dry engine for a while trying to diagnose problems, I have developed a lifter tick that is very noticeable. I assume this could be a t-chain tensioner but it sounds much like a lifter tick. anyone ever have a similar problem or have any advice on why that problem would develop then? | | | | 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 | | | |
