Wanted to drop car off. Here is the problem.
93 Accord with 93 Prelude JDM H22A Automatic swap. This is long but basically just wanted to give you a heads up. I will be stopping by today to have you all look at the car and give me your expert opinion. I realized last night when filling the radiator that it is leaking at the cap area, cheap plastic melted.
While waiting on the ramp I see...and smell smoke, oil burning smell coming from tail pipe. I look behind and it's me. So I pull over check the radiator and it is cool. Look a the overflow tank and it is full, not at max level but full nearly to the top. So I take the oil cap off and smoke is coming from the head and that awful burnt oil smell. I need to get to traffic court so I let the car cool down and slowly cross the street. Court lasted about 2 1/2 hrs. got back in the car started it up and everything is fine. Stop at QT have way to double check everything is good. So I pick up my kids and about 5-10 minutes later I get the smoke again and this time the D4 light is flashing along with CEL on. Flashing D4, I have not check the code, but probably TCU. I noticed the smoke is heaviest when I am decelerating and taking my foot off of the gas pedal. So go back to previous weekend. I changed the oil with Mobil 1 Full Synthetic. Must have had a brain fart because I put 5w 30 in the H22. Supposed to take 10w 30/40. So I was going to change out this weekend but yesterday stopped by the autoparts and picked up some 10w 40, I drive 80 miles daily in traffic so wanted extra heat protection, and filter. I changed the two this morning before going to work. I drove approximately 30 minutes straight and Ironically the D4 light started flashing in the same spt, passing Memorial Drive, then the CEL and then the smoking. Could it be the valve seals are going and letting oil go straight thru to the exahust.
I was letting the car cool down and wife called...ran out of gas. What was funny though is that I was home for about an hour and had to go back out. The car did not smoke going/coming to give wife gas. Not one time. But what I did notice is that when I was about 10 minutes from home I started seeing smoke coming from the hood. I immediately pulled over and it was coming from the rad cap. The coolant in the overflow was at the top and was actually boiling. Soooooooooo, seems like too much water was in the system. So possibly the engine was getting hotter than normal and oil burning off, not sure. Ironcially I had some coolant in the car and added it to the radiator. Matter of fact I had pretty much a full container and the radiator took the whole container. So apparently there was wayyyyy too much water in the system and it simply boiled off. So I am going to bleed the system and add proper coolant/water mixture.
