Eureka!! pressure was at 8 level in cyl 4 whereas the rest of the 5 cylinders are pumping 11 to 12. So, top overhaul began and stranded my UDM for about 5 days. What happened was one of the exhaust valves on cyl 4 had a cracked on the trumpet part. You can actually see thru the valve...heh heh. There was also a "crack menanti belah" on cyl 5 as well. So, changed the valves to new ones and did the grinding on all of the valves. Of course replaced some of the typical gaskets on the way. Now no more misfire, idle is creamy smooth and engine gives more punch. Mileage was 240,000 km. Havent got the bill yet. But can expect about RM3k plus...hisk hisk</p></blockquote><p></p>
