go glean the engine well, and the undercarriage. Take her for a boot and park it. If there are oil stains where you park it , throw some cardboard under the engine area so you have a clear canvas to inspect after. Is there any condensation on the oil cap or neck when the engine is at normal op temp? if there is , LIM leak definately, it gums up the sensor in the rad side and it is designed to throw the warning for that. Do the LIM and all other top end gaskets, clean your intake up, and dont forget that that pcv valve is gonna be gummed up too.
I used Fel Pro for all my gaskets, which are phenominal. Took me , a carpenter, 9 hours to change all necessary gaskets and do the oil change and the rad flush etc. in the freezing winter. Its not a hard job just keep organized and clean the surfaces properly!!! good luck with her!
ps i think the felpro kit came with o rings for injectors as well, while youre removing her.
