hi everyone.
i came across this forum while browsing for solutions to my loss of power problem. (i spotted a posting from 2004 describing my very issue) so i hope somebody out there can help me.
i have a 1976 3.8l mercedes engine which loses power after running for 20 or so miles, it gradually gets less and less powerful until eventually it stalls. after sitting for maybe half hour, it will run again, however not for long before it misbehaves in the same way.
i have renewed the fuel filter, had the fuel lines blown out, used a diesel treatment to clean the injectors etc, given an oil and filter change and use an engine flush, and renewed the oil in the bath filter. i can't find any blockages or collapsed hoses or anything in the air intake side of things... the exhaust isn't excessive or black, or blue....
everybody i have asked so far just goes "thats wierd" and thats as far as i get! lol. i am not an experienced mechanic and i am learning as i go along, so.. laymans terms please!!!! lol.
has anyone experienced this problem? and if so how did you fix it???? we love our old bus and want it well again.
thanks in advance, laura xxx

'Listed a Perkins T6.354 on DieselEngineTrader and sold it after 5 month. With a listing fee of $5.00 per month and no commission, it was much cheaper and more effective than the magazine we also used.'
