Re: 155 TS rough idle and performance down
What's the reason for the rebuild? Did you have a cambelt breaking? It could be they didn't rebuild it quite as they should have...
low compression on one cylinder, so check the sparkplugs are tight on that cylinder. Could also very well be a burned valve.
Do you see white smoke coming from the exhaust, or a mayonaise like substance in the coolant? If the head was skimmed improperly during the rebuild I'm sorry to inform you that it'll be going through gaskets like they are made from chocolate. Most likely a valve or sparkplug issue though.
