IDI Engine / Re: Oil pressure lost
« on: Today at 01:13:44 am »
Finally, an afternoon with sun and warmth enough to get under the car and pull the pan.  After doing so I grabbed the oil pump and expected it to wiggle some.  But no, nada, solid as a rock.  I pulled on the pick up tube and the same thing.  No movement at all.

I looked up under the pickup tube with a bright flashlight and there was nothing on the screen, nothing in the oil pan either that might have sucked up there then let go later.  I looked in the little port for the high pressure relief and found nothing.
But that got me thinking, what if the pressure went up past the limit and then the little release mechanism didn't release?  Would that allow the pressure to drop to zero?  I can't understand why I would have lost oil pressure twice at nearly the same point in my route home. 

The conditions would have been similar. cold engine, cold oil, same length of running time and same hard bump in the road.

Offer your theory if you care to do so.  I am going to run it as it is and hope for the best.

Is the smoke black and comes out only when floored?  You can adjust the fuel going into the injectors and stop that.  If it is more of a bluish tint to it then you may be looking at rebuilding the engine pistons and rings.  How easy does it start?

Do you have a way to check for compression?  Do you notice high oil consumption?  Remember check oil when refueling...I think it is written on the label that surrounds the fuel filler hole.

Are you even asking for assistance here or just stating the facts as you look up to them mirror?

EJslava,  Your vehicle, 98 civic dx 5spd d16y7stock, is not a diesel that I know of.  Why would you even post to this forum?

Because you are a bot I suspect.

Yepper, I bet the majority of poor starting in the cold problems are caused by the fact that you don't have 4 plugs a glowing.  Glad you got it fired up.  Cussing at a car doesn't do any good by the way.  It generally does more harm to you than good.  It might cost you a knuckle or two as well. 

That has been my experience over the last 40 or so years.

I thought someone just was super evil and tagged his ride.

Without the use of that cold start lever you are missing out on a few degrees of advance.  Bumping the pump to make it like that all the time is not what you want.  You want to be able to manually invoke that extra few degrees without relying on the internals of the pump pressure and such to get it to you.

I know getting that lever good and functional is like a major PITA but, if you are that cold then you NEED that lever working.  Some pumps even had the high idle bump mechanism on it too so that would be an ever better thing as you could have the engine purring a bit higher RPM's while cleaning the windshield and it would warm up faster.  Likely about the time you crawled back inside. 

I would for sure be testing the GP's and that system.  With the dual batteries there is no reason why that thing shouldn't be firing right up.

That's the plan, pull the pan.  But with gusting winds of near 45 mph and rain being driven into the windows and down my neck right now I think I will hold off for a few days and let this storm track ride on by.  I will update after I find something.  Good or bad.

Mechanical, comes off a tee at the same place as the pressure switch, @ the head.

I wish I could slap my forehead and go, Yah, that's it.  But the oil pressure gauge at the top of the head is confirming the light on the dash.  Gauge drops to zero as the red dot glows.

I would be inclined to buy it.  My logic is that it was fully oiled for awhile before it's abnormal travels.  The engine likely didn't run for long after the disorientation.  So the damage from no oil would be minimal.  I might be more concerned about cracked flanges or oil filter mount torn off.

Sounds like you might have finally found your engine swap.

What the car or the problem?

The first time this happened I did pull the dipstick, it is the stock one, and it was a qt low so I added that much from the emergency bottle in the trunk.  That stopped it from popping the light on, but I think it was more about the vac pump engaging with the oil shaft.  I have the older diaphragm pump style vac pump on the engine.  It is all in tip top shape as I just tore it apart to figure out why it was detaching from the oil pump drive shaft.

We are scheduled for rain for the next 3 to 4 days so laying on the driveway might be out unless I get on it first thing in the morning. I would have been able to do it today but swapped my work day from Sat to today so I didn't have to dig holes in the rain or lay on my back under a mobile home in the rain.  Good that the Rabbit only needs to go a short distance to get me to work.  The Caddy has brake issues so I am holding off on driving that for a bit.  Need a new proportioning valve. 

I think I will pull the pan and see if the pump is loose.  That is the most direct route.  It pumps good pressure as it gives me close to 100 psi on start up and about 40 at idle hot.  I think I have adjusted the valve in the bottom of the pump in the past. 

AS Always Libby, Great Response!  The voice of experience and reason is always welcome to be heard.

Mechaphelia =  The overwhelming need to have an emotional or sexual relationship with a car is referred to as mechanophilia or mechaphilia. And its actually more popular than youd imagine.

We live in such a weird world.

IDI Engine / Oil pressure lost
« on: February 06, 2019, 12:54:48 am »
I thought I had this problem figured out the other day but it happened to me again tonight on the way home.
As I leave work I drive slowly through a puddle of water that is about 3 inches deep.  I know there is a place where there is a crack or a hole that causes the front end to drop a few inches so I don't want to be racing through and do damage to the car.  But what happens as the front end does that quick drop is that I then loose oil pressure.

If I continue the few feet around the corner and turn the engine off then back on I can generally get the pressure to come back up again.  Trying to figure out what is going on here.

I removed the vane style vacuum pump last weekend and shimmed it up so that the gear would not jump back up about a half an inch.  I am wondering if the oil pump itself is loose from the block and dropping out of the vane pump.  I did get a pair of vise grips on the shaft and pushed and pulled on it from above and didn't get any movement. 

Just wondering if removing the pan and checking for a loose pump is worth laying in the rain in the driveway.  I have other vehicles to drive but this needs to be fixed as I am looking to sell it in the spring. 

Let me know if you have had this same problem and what the fix was that made it go away.
