TLDI forced oil feeding?

[jshoes52]

After the winter lay-up, do I need to force feed the engine oil before starting the motor for the first time this year? It's been fogged and stored since last November.

It's possible that you could develop an air bubble in the feedline from sitting. If you run it by your local dealer they can use a code from the ignition switch to prime the line.

Feel free to correct me if I am wrong here Elvin-<br /><br />The oil injection system on any TLDI is multipoint. In line in each of those oil lines is a check valve. As long as the oil reservoir has oil in it there should be little chance that air will introduce itself into the system. Outside of that, the only way air could get into the sytem would be if there was an oil line leak somewhere allowing air to enter the system. <br /><br />For my own TLDI, I just make sure there is oil in the reservior- and start it and go.

Your not wrong, but it is Tohatsu policy to always check and bleed the TLDI system if the engine has been sitting for an extended period of time.

The bleeding procedure is explained in the owner's manual. So if I bleed it, (and I never have the previous 3 years I've owned), should I expect smoke on start-up, or is the oil fed beyond the point of combustion, being a dfi 2 stroke?

Your bleeding the oil system...That's all your doing. It does not put extra oil anywhere.

To expand on what Elvin is saying:<br />The bleeding procedure only clears potential bubbles from the oil reservoir to the oil pump.<br /><br />There is a bleed screw (bolt) on the oil pump itself and it allows oil to flow freely (or not so freely) from the reservoir to the pump eliminating any bubbles in that line. When you open that bleeder screw, you will see oil seep slowly from the top of the oil pump. It then proceeds to make a mess if you do not have a rag underneath the oil pump. Again, if your oil reservoir is full and the engine has been left upright, It would be near impossible for air bubbles to enter the system (unless something is really wrong). After the oil pump, there are those checks valves I was talking about.

Jshoes52-<br /><br />After reading your posts again, the answer is "no", this is not a procedure that primes the oil system by giving the engine a shot of extra oil at season start up.
