RX7 FD water in engine
Hello,
In October, I bought a RX7 FD from Britain. In 2009 the company made overhaul in the UK , yet not mention the company name. The car I drove approx. 1000 km. Before each ride, I checked the oil and water level. I had to water regularly topped up using about. 0.2 l. Car doesn´t smoked and started well, so I paid no attention. During a car ride I got to 120 degrees Celsius. I immediately shut down and waited for her to cool down. I refilled one liter of water and slowly wandered into the garage. The temperature was kept throughout the 86 degrees celsius. At home, I took off the exhaust manifold and the hand spinning rotor. From the combustion chamber spilled water. Pressures measured and are good. I motor slowly demount. Do you think it will be bad just water seal? The oil doesn´t loosing. Sorry for my bad english. WTF :lol:? http://img571.imageshack.us/img571/5550/krca.jpg Reducing oil flow to turbo? http://img46.imageshack.us/img46/6084/m2oi.jpg http://img812.imageshack.us/img812/1269/ofu7.jpg http://img191.imageshack.us/img191/3843/it12.jpg With my ST185 http://img855.imageshack.us/img855/820/txsz.jpg http://img853.imageshack.us/img853/487/h204.jpg |
Jak se mas? Don't worry about your English, it's better than some posts here from those with English as a first language. And way better than my Czech.
You have a coolant seal failure which will require disassembly of the engine. I would suggest not waiting too long to fix it. Having coolant sit in the grooves of the side plates can cause rust and make the side plates unusable. You might look up a member named Metan here on the forum. He's also from the Czech Republic and may be able to help you find a reliable mechanic or give advice with the rebuild. |
Ahoj Sgtblue, mám se dobře :nod:
Yesterday I pulled the engine out of the car. http://img30.imageshack.us/img30/4518/7omd.jpg http://img94.imageshack.us/img94/1857/2v21.jpg http://img845.imageshack.us/img845/7915/x9cq.jpg http://img35.imageshack.us/img35/3808/l0cx.jpg [URL=http://imageshack.us/photo/my-images/11/a55c.jpg/]http://img11.imageshack.us/img11/3508/a55c.jpg[/UR In this week i wont to complete dismantle the engine. |
Good progress. Looks like a previous owner installed a lightened flywheel. :icon_tup:
A couple of tips....that front hub bolt can be really hard to remove. If you haven't gotten it off yet, I strongly recommend using a 6-sided wrench or socket...not 12 sided. Those can slip and round off that nut. |
Coolant seal
Might be the coolant seal those tend to fail after some time

Bearings in stationary gear looks bad. http://imageshack.com/scaled/1024x768/189/rhnu.jpg Dust http://imageshack.com/scaled/1024x768/841/7ew3.jpg http://imageshack.com/scaled/1024x768/89/bn32.jpg http://imageshack.com/scaled/1024x768/202/nkhx.jpg http://imageshack.com/scaled/1024x768/7/km2n.jpg http://imageshack.com/scaled/1024x768/707/cekm.jpg Speedometer shows in miles, do You know how to remake the km/h? http://imageshack.com/scaled/1024x768/837/7zvz.jpg |
Plates measured and seems great.

The sound came from the gearbox, which brushed the body see photo http://imagizer.imageshack.us/v2/102...0/855/h6tc.jpg Boys nicely blinded EGR. Only one screw from 3 to split them and bother them unscrewed and rewind thread. It seems that the resulting flue gas leak leaked and possibly i nespálený olej. http://imagizer.imageshack.us/v2/102...0/853/0g7b.jpg http://imagizer.imageshack.us/v2/102...0/163/zm6p.jpg I forgot to put there rotors :nod: http://imagizer.imageshack.us/v2/102...90/24/06rs.jpg https://imagizer.imageshack.us/v2/10...90/89/5c9x.jpg[/url] https://imagizer.imageshack.us/v2/10...0/854/9cjf.jpg Now I´am choosing APEX seals, side seals and corner seals: 1. RA super seals RA Super Seals 2. Atkins Apex seals 86-95 Rx7 13B 2mm Atkins Apex Seal Set (ARE13-2) 3. 86-95 Rx7 13B Side Seal Set (N3Y1-11-C11) 4. 86-95 Rx7 13B 2mm Solid Corner Seal Set (ARE88) Do You know why my old corner seal broke up? This is old power graph. http://imagizer.imageshack.us/v2/102...90/17/uhdy.jpg |
I posted in your other Thread,Matty.
look at these:https://www.rx7club.com/vendor-class...-seals-946394/ |
Old corner seal is destroyed due to the detonation?
That is why I will refuel high-octane gasoline to prevent detonation. Filling pressure I do not want to reduce. I ordered the RA super seal + springs. From banzai new ast + oil pan brace. From Atkins every seals and all other necessary parts. I ordered the small things in Mazda in the Czech Republic. I hope that in March the engine will be ready. Do you know what runout mm will be the bearing in the clutch shaft in the gearbox? In the manual, I don´t found it. |

My last motor did that! Atkins took a bunch of my money but fixed it. How much did it cost you?
