SUMMIT CRUISERS Jr
SILVER Star
Over the past several months, an injector leak stared to develop. I was worried because gas was dripping down above the exhaust. I ordered Osidetiger injectors after talking to a guy locally who went with these injectors on his 3FE powered Fj62, and new gaskets from @cruiserdan
We started taking apart everything at 9:30 in the morning and finished the install 10 hours later.
This was the most disassembled this engine has been in its 361,000 miles. While apart, we cleaned the fuel rail, injector cups and all little parts in there. We also tried removing most of the already deactivated EGR stuff, but couldn't find the caps needed locally.
New and old
New is on the left and old is on the right.
Using an oring lube on all the injectors, and dielectric grease on the connections. All the old plastic ones were just breaking to piece when we pulled them off, so we used zip ties to make sure they wouldn't come loose.
The install went pretty good until tightening the intake back down. Using a torque wrench at the required spec in the FSM, one tired bolt just broke before it was tight. I would recommend buying new bolts if you are replacing injectors/gaskets to save a lot of headache.
The truck seems to start up smoother and quicker, and also has a little bit better throttle response initially. It also seems to be smoother while idling. Haven't driven it much since the install, but hopefully fuel mileage will stay the same, if not improve.
