Question about 1988 Jeep Wrangler
At Idle everything seems fine, timing is 8-12 btdc and idle is around 750 -800. When I take it for a ride at highway speed It looses power around 3,000 to 4,000 rpm and looses oil pressure. When I return to the garage there is tons of oil inside the air cleaner and when I check oil level it is lower but seems to be like air bubbly. Please help, not sure what to think
Hello, I believe I can help you with this problem. The oil in the air cleaner is "blow-by" from the piston rings. This is a common problem on your engine. There are 2 breathers built into your valve cover, the rearward one is the PCV valve and is most likely clogged up causing the front causing the crankcase pressure to go through the front breather and on into your air filter. Chrysler sells the parts you need as a kit, with the grommets for the valve cover and the vacuum hoses to refresh your system. You will need to remove the valve cover and clean the inside of it, then replace the grommets and hoses to the air cleaner. If this doesn't work you might need to replace the entire valve cover assembly. This is most likely causing your performance issues also. Good luck and don't hesitate to ask for more information, I'll be glad to help.
