'89 Renix 2wd Comanche with 4.0 6cyl and Aisin AX-15 manual 5 speed MFI 242 What advice can y'all offer on replacing/repairing the exhaust manifold on a 89' renix comanche? I haven't torn it all apart yet, but I'd like to be readied for the worst if it winds up as more than the perfunctory gasket replacement we're most familiar with. Exhaust fumes were noticed emanating from underneath the hood when parking my vehicle directly after 15 minutes of highway driving in heavy rain. I heard no distinct, loud, or obscene sound, but upon parking the smell of fumes was noticed as immediately as the now visible tendrils of fumes escaping on the driver's side from the crevice a closed hood rests inside. The vehicle was promptly parked awaiting its trial so as to prevent damage to my catalytic converter, the rest of the exhaust, system, vapor canister, EGR, system or throttle body. The replacement parts seem either too cheaply made, probably won't bolt on squarely, could need serious modification to correctly fit, and may require parts, such as a drill and tap; or they're strictly for a 91' + MJ/XJ though I'm in no way opposed to using the existing replacement gasket options. I'm experiencing hellacious blow-by and will be replacing the valve cover gasket and following Cruiser54's valve cover mod most likely tomorrow. As a side query what solution has worked for you replacing the air intake?
