I recommend the MLS gasket that Denis Welch supplies. It requires a very smooth finish, but if you can get that it provides a very good seal. I had the chronic problem of a leaky head gasket on my 100 And their gasket solved it. </div>

<p class="x_MsoNormal"><span style="color:#1F497D">did the job perfectly. Attached is an image of where my builder put it, rolling the block to place the product where he deduced the seepage came through. In this specific use, I do not think there was much
change in heat transfer. It worked for years, then I sold the car but suspect it is still doing the job. Jim Wojcik, MN</span></p>

<p class="x_MsoNormal">Approx 15k mi on rebuilt engine by PO.</p>

<div>
<p class="x_MsoNormal">Recently detected water droplets and creamy oil residue inside valve cover and near oil filler.</p>
</div>
<div>
<p class="x_MsoNormal">Pains as engine and car run so well ... grr</p>
</div>
<div>
<p class="x_MsoNormal">Did compression test and all OK at around 150 psi</p>
</div>
<div>
<p class="x_MsoNormal">Also had oil analysis done that confirmed glycol in oil. Interesting no water found ... assume gets burnt off ?</p>
</div>
<div>
<p class="x_MsoNormal">Upon reflection realise had been losing some coolant. Have recently installed a recovery reservoir and attributed the loss to air being removed. Silly me.</p>
</div>
<div>
<p class="x_MsoNormal">So need some ideas how to proceed and if there is a likely culprit area that others may have encountered ?</p>
</div>
<div>
<p class="x_MsoNormal"> Maybe start by re torqueing the head ?</p>
</div>
<div>
<p class="x_MsoNormal">Not sure how to retest though apart from another oil test.</p>
</div>
<div>
<p class="x_MsoNormal">Remove head ?</p>
